Is there a paint-by-numbers guide to using the NHC internal system?
I'm back-scoring last seasons results to see what alternatives we
might use to our regular PHRF system. So, we have five monthly
series of four weekly races each. I set the first one to NHC
(internal), set up a column for new rating, and then rescored.
There were values in the new rating column, which I guess might be
the end result after rescoring the four races. If I print each
race, we get a succession of rating changes, but the new rating
column stays the same, of course.
I assume that to get from the May series to the June series, I must
manually enter the final new rating from May into the rating values
for June?
Finally, is there an explanation of how the adjusted TCF is
This has some documentation and also a link to the RYA page with the description of the NHC which contains how it is calculated.

The New rating is always the rating that is to be used for the next race.
If you want to see and or print the ratings to see how they change race by race press F6 then r and they are all displayed. You can then publish and print these if you like.
There is a sample in the examples you can play with and don’t forget you can dual score so use both your normal and NHC
*I assume that to get from the May series to the June series, I must manually enter the final new rating from May into the rating values for June? *
The new rating column at the end of the series then goes into the ratings for Race 1 (Not the rating column - this is the base rating)
Normally the easy way to do this at the end of the series is to copy the file and then delete all races except the blank one at the end (NHC always must have 1 more race than there are races) This then becomes Race 1 of the new series and all the ratings are in there Press F6 and then r to check.
Because you already have results in your new file you will need to enter them into the Race 1 manually this is not as big a job as it sounds if you sort them in a known order and then press F6 r and edit the top one and then you can just go down arrow enter to edit the next one.
If you need any help send me your blw file and I’ll have a look
Unfortunately I have not yet been able to set up our club’s Personal Handicap system for some of our club dinghy racing. When I asked about this before Christmas, it was suggested I use the NHC system on top of the RYA PY numbers.
I have also seen mention of “dual scoring” using aliases. I have not worked out how these work. Before I try, Is it possible to “dual score” with a locally modified RYA PY Ratings file and NHC modified ratings?
I think I will need a guide on setting up the dual scoring if this is possible.

Big boats tend to talk about Divisions where asdDinghy sailing
tends to talk about Fleets. Both mean mean a group of boats that
are scored against each other under some rating system or not as
the case may be.
Using your description of what you want to achieve, one Fleet
will those using the ‘standard’ [e.g . RYA Portsmouth]
rating and this will probably be the first set of competitors you
entered. The second Fleet will competitor aliases of the
competitors already entered and then scored using the RYA NHC
rating system. Using aliases as has already been mentions means
you only have to enter the finish times once for each physical
boat/competitor.
By default the aliases functionality is switched off and is
turned on my clicking Set up on the menu bar followed by clicking
the option User interface. In the window that opens, click the box
alongside ‘Competitor aliasing’ followed by OK.
To create aliases of the all or some of the competitors in the
file click Edit on menu bar followed by selecting New competitor
aliasing. In the window that opens select the competitors you want
to create an alias of.
Once you have aliased competitors you will need to set the Fleet
field to for example ‘NHC Rating’.
Hope that helps get you started.

Thanks for all your help with this. The PY modifications certainly look better with version 1.9.1 of swhelper.exe. As I had updated to the latest Sailwave on Thursday (V2-25-11), I assumed that it would all be up-to-date.
Any suggestions you can give to help me get more of an improvement will be much appreciated.

Thanks for your continuing help. Still working on dual NHC and PHRF
dual scoring.
The PHRF system around here is time on time, with the TCF =
650/(Rating + 520). For my test data set, I switched the initial
PHRF ratings from numbers like 54, 81, 105 to the TCF equivalents:
1.1324, 1.0815 and 1.0400. I set the scoring system to NHC
Internal. Then I scored the four race series, and noted the rating
changes. I was happy to see the TCFs for the two Farr 30s that win
everything move from 1.1324 to 1.167 and 1.170.
It would be more effective for discussion if I were able to present
the revised ratings as PHRF numbers instead of TCF. In this case
the two ratings move from 54 t0 36 and 37. Back in the day this
used to mean “seconds per mile”, and when the local handicappers
would consider changing a rating the fights would be furious over 3
seconds. So a drop from 54 to 36 is pretty earth-shaking.
Anyway, with spreadsheets anything is possible, but before I move
down that path I wanted to make sure you haven’t already dealt with
this. I admit I haven’t explored the NHC External systems, which is
maybe where I should look next. I’d appreciate your advice.
Thanks,

The New rating is always the rating that is to be used for the
next race.
If you want to see and or print the ratings to see how they
change race by race press F6 then r and they are all
displayed. You can then publish and print these if you like.
There is a sample in the examples you can play with and
don’t forget you can dual score so use both your normal and
NHC

The new rating column at the end of the series then goes into
the ratings for Race 1 (Not the rating column - this is
the base rating)
Normally the easy way to do this at the end of the series
is to copy the file and then delete all races except the blank
one at the end (NHC always must have 1 more race than there
are races) This then becomes Race 1 of the new series and all
the ratings are in there Press F6 and then r to check.
Because you already have results in your new file you will
need to enter them into the Race 1 manually this is not as big
a job as it sounds if you sort them in a known order and then
press F6 r and edit the top one and then you can just go down
arrow enter to edit the next one.

However, Sailwave NHC will do an auto conversion from PY (1000 based) or VYC 100 based ratings
The way it works if the ratings are around the 1 then it assumes it is TCF.
If the ratings are around the 1000 then it assumes PY if they are around 100 then it assumes VYC
It then converts the ratings to TCF to do the calculation and then converts them back at the end
So it’s not going to work automatically in your case but using the external method there is a competitor field new rating which can be populated separately from next rating (realigned) that it will use. In the config worksheet. Normally these are the same but you could easily create a new column in the Main Worksheet with the PHRF rating in it and then change the Config worksheet to point to this new column and you will have PHRF ratings displayed in the NewRating competitor field which you can publish.
This would be very easy to implement if you want to go the full route of converting the ratings using a custom template then this would also be possible but a bit more work.
Let me know if this will work for you and if you need any help

Thanks for all your help with this. The PY modifications certainly look better with version 1.9.1 of swhelper.exe. As I had updated to the latest Sailwave on Thursday (V2-25-11), I assumed that it would all be up-to-date.
Any suggestions you can give to help me get more of an improvement will be much appreciated.
I had seen and used the r keyboard shortcut to display the rating values. It would be good to get your opinion on my set-up… Please find attached the blw file.
I was a but confused by some of the adjustments, particularly:
Vareo 516 Rating increased, despite winning every race he has entered!
I think I have now managed to set up the Aliases and the NCH scoring for one of the fleets as I wanted. The rating adjustment seems to be doing something to the results, I will have to workout if it is what we want by testing on some past series files I have.
Unfortunately I have not yet been able to set up our club’s Personal Handicap system for some of our club dinghy racing. When I asked about this before Christmas, it was suggested I use the NHC system on top of the RYA PY numbers.
I have also seen mention of “dual scoring” using aliases. I have not worked out how these work. Before I try, Is it possible to “dual score” with a locally modified RYA PY Ratings file and NHC modified ratings?
I think I will need a guide on setting up the dual scoring if this is possible…
Thanks in advance,
Mark Warren…
