Hi
I would like to start using personal handicaps in Sailwave. I have a 10 race series set of results to analysis and come up with personal handicaps.
Q1) How can I work out the personal handicaps? I have looked at “Tools->Assign personal handicaps” but do not really understand the output or screen. How are the handicaps worked out.
Q2) For a new series, how can I score competitors against their PY and then against their personal handicap. I do not want to enter all races twice over. (One posting talked about aliases but I cannot find this).
I am looking for a process to be able to do this with Sailwave. I am an experienced user and good at software, so just need a few pointers for the menu options I am missing.
Thank you in advance for your help.
Hi Rosemary
As you correctly said there is a on option on the menu to apply Personal handicaps.

Sailwave has the ability to have a default rating(handicap) and the ability to override this handicap for individual races
So you can specify a handicap for each race for a competitor.
In its simplest form you can manually change the rating for each competitor as you wish.
One of the parameters that Sailwave calculates is a BCR Back Corrected Rating - This is the rating that you would need to have to have had to be equal first. So with the above tool you can apply a formula to adjust the rating for a specified race.
You could do this after each race or may be at the end of a series so the new rating is used for the next series.
Now the more sophisticated method is to use the RYA NHC specification. This adjusts the rating for each race based on the performance of the competitors. Please see the Sailwave web site and this forum for the many details and discussions on NHC.
Sailwave can use an Alias for Dual scoring where you enter the results for a competitor against the main competitor and it applies the same results to an Alias of this competitor automatically. The Alias can be the personal handicap version using NHC rating system
So you can then produce dual scoring (or even triple) results automatically.

Hi Jon
Can I pursue this discussion a little.
1 The defauls equation in the Personal Handicap box appears to be prevbcr * 0.9. How does this work please? I understand the prevbcr bit but how does 0.9 factor operate?
2 We have used this default equation and applied it to all races in a series. Looking at the rating values through the series they are very variable and while they may be relatively consistent between competitors there appears to be no normalisation to render them useful to let competitors know if they are getting better or not. Are we doing it right? Last year we used the NHC process but hoped the option within Sailwave would be easier to operate.
Many thanks

Hi Ian,
BCR is short for Back Corrected Rating which is rating that they would have needed to be joint first.
So lets take an example
Using the elapsed example supplied with Sailwave
Switch the display to BCR
![Inline images 2]()
we see
![Inline images 1]()
The Tools assign personal handicap tool is then
![Inline images 3]()
You can create you own expression prevbcr * 0.9 is just an example
![Inline images 4]()
You see the rating for R6 are now the previous BCR * 0.9 Some have gone up and some have gone down
To get a better result you could use the avebcr and average them over a specific number.
This is much more of a manual system than the NHC - This is really an aid. NHC is a much more sophisticated system

Thanks Jon
I couldn’t see your images or find the elapsed example but no matter - I followed your steps in our own series and now understand how it works.
Thanks
Ian
Hi Ian,
I’ve sent you a personal email with the images. You need to have emails from the User Group turned on to receive the images. The Forum software strips them out when you view them online but it does send them out with the emails
The elapsed example is installed with Sailwave which will be in the examples folder.
