PHRF ToT

d.trude · 26 September 2015 00:18

I’ve used sail wave for Opti regattas and it is pretty straight forward for OD racing.

However our club wants to start using something different than the member created excel spreadsheet for our scoring system next year.

We are in SO Cal and use PHRF. I have entered a small race of 9 boats, ratings, distance start and finish times. I cannot figure out how to display the time allowance, Elapsed and corrected times. I understand the column edit function but I cannot find these columns.

I have double clicked on the Race Column, entered all the info and see all the info but the Corrected Times do not seem to be calculating.

Also, where do I find out how to make a Rating File?

Thanks Dave

Also in So. Calif.

ToT scoring uses TCFs so I would recommend calculating your TCFs in
Excel and posting the PHRF rating and corresponding TCF for each boat.
That makes the process transparent to the competitors. Sailwave can do
it internally but it doesn't display the TCFs in the results so sailors
cannot check that the math is correct. On your results I think you'll
want to see "Rating" (meaning TCF), "Finish," "Elapsed" and "Corrected."
We also like to show BCE (Back Corrected Elapsed), which displays the
time out of first (which isn't straight-forward when using TCFs to score).

Under "Setup|Scoring system" go to the "Rating system" tab and choose
"TCF" (if you need different scoring systems for different classes then
go to the "Fleets" tab and customize). For each boat, enter the TCF
under "Rating" (double click on a boat in normal view or go to
"Edit|Edit competitor"). After scoring you publish and there are
options. Under "Publish|<whatever template you use>" there is an
"Options" tab where you can show corrected times and other stuff. This
is where you select BCE if you want it. We rename the BCE column title
to "1st+" as the meaning is more obvious than "BCE." I don't think
Sailwave can display the "time allowances" (being the Elapsed time minus
the Corrected time) but someone else can correct me if I'm wrong.

In theory you can do ratings with a rating files but I think you'll save
a lot of time by just creating a master BLW file with all boats and all
ratings entered and then for each regatta just delete the boats that
don't sail. We always enter (or verify) each boat's rating by hand and
it takes minutes per event (since SoCal PHRF ratings can change at any
time you pretty much have to look them up and verify them for every
event anyways; other places in the world only change ratings once per
year so using a rating file makes sense there). If you have 100+
different boats in every event then a rating file might make sense but
otherwise doing it manually only takes a short time a day or so ahead of
time. SoCal PHRF doesn't publish a ratings file that you can just
download and use, if it did then you might consider using one.

Thanks for all that. It made me look deeper and I found that our area is using ToD like most in the USA.

I got things worked out and you can see the publishing at my site (testing)
http://www.webbdawg.com/sw/vyc2015govcup.htm

The race was originally scored using a member created Spreadsheet that you can compare here

http://www.venturayachtclub.org/sites/default/files/GovCupResults.pdf

I wish you could see the published results like that in the program.

I have noticed that the corrected times are a few seconds different, 4 seconds max from the YC results.
I am asking out how the YC spreadsheet computes the race distance as it is nautical miles. It seems you need to get down to sec/ft to properly calculate the time allowance correctly.

One thing I did find was when Printing there seems to be some code that prints each table to a separate sheet. I tried this in Chrome and IE.

Is it possible to print the HTML when there are small fleets to not use so much paper? Just trying to be ECO.

I am going to try and talk our area in to ToT because we have small fleets that have a wide range of ratings.

Thanks.

[Please include what you are replying to when you reply as otherwise

I checked the results for a couple of boats and my calculations agree
with the Sailwave calculations. Apparently, the formula used in your
spreadsheet seems to be off somehow (which is a good reason to be
cautious when scoring with Excel).

Under "Publish|<the template you use>" look on the "What to publish"
tab. Do you have "Add a page breaks" checked? I believe that will add
page breaks so classes won't be split over two pages when printing. That
might be your problem.

In typical conditions, TimeOnDistance and TimeOnTime are equally
accurate in So. Calif. (because there is no significant current like
with tides or in a river). ToT can, in theory, be more accurate when the
conditions are significantly different from normal, like a very
light-air race in your area. You have to balance the convenience and
simplicity of ToD scoring vs. the increased theoretical accuracy of ToT
when there are highly unusual conditions. My experience in So. Calif. is
that we have pretty steady conditions so it make sense to prefer
simplicity in all races to increased accuracy in a few races. But, as an
experienced and more tech-savvy racer I'd be indifferent to whether ToT
or ToD is used (ToD is definitely better for the lower-end racers).

Art, I thought I was responding to the last post in this thread.
You have to understand that Yahoo Groups really suck

I am using ToD now.

as you seen the previous race that I published (http://www.webbdawg.com/sw/vyc2015govcup.htm) and everything seemed to work fine, I have started to work on a regatta of 3 races to make sure it works too.

I cannot get the Corrected times to calculate. Sailwave results for 2015 Ventura Cup / Santa Barbara Channel Challenge at 2015

I’m not sure why I cannot get the Corrected times to calculate.

Hi Dave,

I’m sure that somebody will be able to help you if you would post the actual Sailwave file.
