ORC ratings file template

HI all, ORC scoring is easily done with a couple of work arounds. I have one SW file with OCR Triple AP ratings at Medium wind and the second race in the series is scored with ORC W/L low wind. (you read in the two proper rating from the registration csv page). I know I can merge final results from the two races into one new blw file and rescore all the races based on final position. Is there a way to keep the specific race calculations in the merge.

There are some obvious upgrades that would be nice. The most important one is managing the other ORC ratings tables. Sailwave can manage one. Right now, I import the registration csv into two Blw files. In one table, I map Handicap rating to AP single number and AP triple to Wind ratings. and i repeat the process for the second blw file but for WL formats. I remap to WL single number and WL tripple wind ratings to the sailwave rating and wind speed rating.

Another work around could be to re-import a registration file but NOT overwrite the entered and scored race data? IE these data are locked. This would be a simple fix…You just import the registration csv and remap rating and wind ratings to the proper choice and score your next race. I assume Sailwave does not go back and recalculate previously scored races. based on the updated rating and wind rating values??? I don’t think SW works this way tho.

more random thoughts/questions… Could aliasing help me out here? ( Limited experience using this but I understand it to mean the same results can be aliased to an additional fleet using a seperate scoring systems).

What is the alternate rating field used for and could I repurpose that as a second pair of rating fields (new upgrade since my last experience)?

Any other upgrades that could help?

I think you are over-thinking this. We’ve used so-called “wind-indexing”
locally a few times. For events with different course ratings we use
“buoy,” “random leg” and “offwind” but there is no reason you couldn’t
have “buoy-low,” “buoy-med,” “buoy-high,” etc. Personally, I can’t see
any need for multiple files or aliases or other complications.

I suppose you might want high-windspeed races count twice as much as
other races but I think you’d have to do that on a race by race basis. I
don’t think it could be automated.

If this doesn’t work for you then I think you need to explain what you
are trying to accomplish as I don’t see why the “wind-indexed” option
wouldn’t work.

Art, The club PRO picks from two course configurations W/L and Buoy aka AP and a wind band for Wed night… So… I combine Single number Buoy with Buoy three windspeeds for buoy aka Buoy Low, Buoy Medium and Buoy High. Then you select the wind speed when you edit the particular race. The problem is… .Next week in the series… he selects a WL course and so I open a new blw file, import the competitors and select the single number WL and the WL wind ratings during the import and score that evenings race. Now I have two blw files… I now create a third BLW file and import the race results from R1 and R2’s Blw files and score the series… Very workable but its not an elegant or clean solution.

What would be best for ORC scoring would be for Sailwave to have 4 sets of ratings imported when you read the csv file of competitors. Then each race in a regatta using ORC scoring for the fleet would have you select the ratings band… eg Buoy (aka AP) and then select the wind speed band (or not … if using single number ratings).

Everything else is searching for better work a rounds.

I’m still very confused. Forget the names, lets assume you have 6
ratings for each boat (rating-1 to rating-6, whether different courses
or wind ranges is irrelevant). You put all the information for each boat
(including all 6 ratings) into a CSV file and import into Sailwave.

For race #1 you choose to score with rating-1, for race #2 you choose to
score with rating-6, for race #3 you choose to score with rating-4, etc.
I don’t understand the need for more than one BLW file.

Where do I put the ratings in Sailwave… I know i can map 1 rating to Rating field. and I can map 4 ratings to the windrat field. So that is one of the ORC schemes… eg Buoy races … this is essentially identical to classic portsmouth one single number and 3 wind bands. Where are you mapping the other ORC ratings to in sailwave and how do you use them?

We seem to be talking at cross-purposes. As an example, for 7 ratings
here is what I would do in Sailwave directly:

  1. “Setup|User Interface” enable “Wind indexed ratings”

  2. Go to “Setup|Scoring system|Rating System” and choose TCF (assuming
    you are using Time Correction Factor Scoring but choose whichever option
    is applicable)

  3. Enable “Use wind indexed rating values” and then enter the names for
    your ratings - I used
    “Single,Buoy-L,Buoy-M,Buoy-H,Random-L,Random-M,Random-H” [don’t enter
    the quotes]

  4. Now go to “Edit competitor|Entry” and toward the bottom you will see
    two boxes entitled: “TCF” and “Wind values.” You can ignore the TCF box
    and leave it blank since you won’t be using that. In the other box put
    your 7 ratings. I used “1.0,1.01,1.02,1.03,0.99,0.98,0.97” [don’t enter
    the quotes]

  5. When you set up a race under “Edit|Edit race|R1” you can now pick the
    rating to use since under “Wind index” heading you will have a dropdown
    list with your 7 rating names.

I believe you can do this in a CSV file for import but you’ll have to
play around with that. I seem to recall the wind-indexed ratings needed
to be in single or double quotes but others might know more.

Now for race #1 I can choose “Single” and for race #2 I can pick
“Buoy-H” and for race #3 I can pick “Random-L” etc.

Thank you, Success! I had no idea I could populate the windrat field this way. I edited the competitor excel file by adding a concat function of the matching ratings columns, adding a , and space for making the csv file… I filled it with the 6 wind ratings and import this column to the wind ratings field. Works great! I certainly did not remember this feature.

Am I correct that you can load 9 separate ratings this way?

I am unaware of any limitation on the number of ratings in the
wind-indexed space but my general computer experience would be that
maybe there is a limit of 256 characters - but that is probably more
applicable for the names than the actual ratings field.

Well, I loaded 8 ratings into the windrat field single number and three winds.
I would build a separate blw template for the point to point distance ratings.

I discovered that you can’t merge results from a blw file with a different order of wind speed ratings… It creates another competitor entry.

My final question… Is there anyway to publish the rating used for that race? I can publish the entire field of all 8 4 decimal place numbers… but that is just gibberish to the user looking at an individual race score sheet. You can see the rating used in the audit field for a particular boat. Is there anyway to get that put on the score sheet. Something like a tick box just like BCE or BCR?

In the past we used Wind indexed ratings. To publish the rating used for a individuaL race, set publish Rating column to Yes and select Publish individual race tables. This will leave the Rating field in the summary table blank which might be a bug, but it lists the actual rating used for the race in the individual race table

Yes Pv. From my experience this publishes the complete Wind ratings field but not the exact rating used by selecting the race’s wind range.
What am I missing? (Thanks to Art, I fully understand the wind ratings field.)

IME, it was not pretty using portsmouth with 4 wind ratings (multihulls) but with ORC, I have the field populated with 8 4 decimal point ratings and its down right confusing on the individual race results page.

My hope is that there is way to publish the specific wind rating used. This is the output the club uses from Yacht scoring as well. Granted the utility of publishing the specific rating, elapsed, corrected, BCE and BCR is for the sailor to do their own audit of the scoresheet and their own performance.

Thanks Mark

Hi Mark,

I clearly didn’t explain it correctly. I have a couple links that show what I was trying to say.

Link to results with boats having different ratings (wind rating) from race to race : https://www.dropbox.com/s/t7morv0xzcgfvhy/Sailwave%20results%20for%20Aug%2010-11%20Weekend%20at%20Wabamun%20Sailing%20Club%202021.html?dl=0
Link to the Sailwave that published the html file: https://www.dropbox.com/s/4dxg6d5c4tzj2z1/Aug-10-11-Weekend.blw?dl=0

As you can see the boats’ ratings (wind ratings) change in some of the individual races. The only way you can display that field is by displaying the Rating field which is not the wind rating, it’s the default rating which is not populated in our case. It would be nice if Jon could add to the individual race tables options a “Include rating” check and this would display the rating used to calculate the corrected time for that boat in that race.

I just noticed that the 1st palace BCR is not always the same as the rating. I’m not sure if this is intended.

I hope that this helps.
Peter

HI Peter… Outstanding. Thank you for the links. When you leave the rating field blank…SW populates the result table with the actual rating used from the windspeed rating field in the duh… rating field!.. Once again I had no idea… For portsmouth racing… we used the USA or SCHRS published ratings table database and sucked in each competitors rating from the table. Of course for Portsmouth this populated both DPN into the rating field and the wind ratings into the winrate field … PHRF and SCHRS are single number systems and so we mapped the single rating to the ratings field. So, I never had an unpopulated rating field!

In my hands, Sailwave is selecting the proper wind rating for publishing and the BCR calculation is matching the first place finisher. (Lots of rounding involved with OCR 4 decimal point ratings (grin) ) I noticed the mismatch in your results as well???

One of the problems of being around from the beginning is that you don’t solve the problem with fresh eyes… ever!

Thanks all, its been fun!

Hi all,
Just one thing to note, Sailwave cannot change on a race by race basis the rating formula used. This means you cannot have some races in a series ToT and others ToD, i.e. all races must either be ToT or ToD.

I suspect there is a limit on the number of wind-indexed ratings that can be accommodated in Sailwave, but I am quite confident that if a limit was hit, Jon could raise the limit.

Kind regards,
Huw

Hi Hu… HA… I did know that you can’t mix scoring systems that way! (grin).
I don’t think there is any problem with the number of ratings available in the wind rat field. Eight ratings in the drop down menu is plenty.

My only bit of value add is to make life easy on yourself when you put ratings in Win rate field of your registration file is to add a space in the excell and consequently the csv file between each rating. It does not impact the scoring and it makes looking at the ratings in sailwave doable, especially when you are auditing the results.

Hi Mark,

The first place boats now have the correct BCR. I probably changed a wind band and published the results without rescoring it.
Including a “Include rating” check option for individual race tables would make things a bit cleaner.

Peter

Hi Peter
I am not sure what you would consider a ratings check option.
My version would be display Todays rating field with the wind rating field (hopefully you have added some spaces. between ratings and then eyeball that you have selected the proper wind band for the race.

Hi Mark,

Here is a link to a screen capture that I was thinking about: https://www.dropbox.com/s/ys81hngqyzoco8d/Capture.JPG?dl=0 It would display the actual rating used to calculate the corrected time on the individual race table.

Displaying the rating on the Series summary table doesn’t mean much since with wind based ratings the rating can change from race to race.

Peter

ank Fleet Name Class Sail no Club Helm Today’s rating Ratings Win AP + WL + Sing # Location Elapsed Corrected BCE BCR Points
1 ORC 1 Mummbles Farr 30 USA 35 AYC Brad Kauffman 1.1385 0.9273, 1.1385, 1.2866, 0.7271, 0.928, 1.0568, 1.1392, 0.9255 Annapolis, MD, USA 1.06.38 1.15.52 0.00.00 1.139 1.0

My approach is to print both rating fields… the race info at the top tells me to take the second of the AP or all purpose wind rating. Lets hope the formating comes through! Now I would never want to print this file … but it helps at my first pass at an audit. I change the display and publish the provisional results. Anymore auditing is really a study of my csv registration file… If I screw up the ratings there… It will take a boat owner to notify me that I screwed up their rating somehow on the import.

Now I have often wanted to increase the font of the header for this table.

R1

Start: Start 1, Finishes: Elapsed time, Course: Buoys, Wind strength: AP Med, Ave wind: Medium

I have thought that this formatting could use a refresh but all of the info you need can be displayed so… not a big issue.
