We run two fleets which are both scored together and separately. We have been using manually calculated progressive handicaps but I have been testing using RYA NHC in Sailwave instead. I am using the actual results from our second series which experienced several light wind races. However, I am getting anomolous results:
The handicaps for the Multihull don’t change from the initial setting, while the Monohull does.
One of the monohulls develops a negative handicap. The only issue I can find with this boat is he showed everyone the way round the course by a long way in Race one.
Thanks, Jon. The scoring of both fleets together was intentional as we run both fleet and overall scoring.
I re-ran using your editted file and got the same screwy results so I decided something must have got corrupted in my installation. I reinstalled the latest Sailwave (which I already had) and then re-ran the scoring.
Low and behold, the results now look fine, so it looks as though corruption somewhere was the issue.
Many thanks for your help, and for all the hardwork you do for the Forum.

The results you have shown in your email obviously don’t come from the same file as the file you attached. The file you attached has a DNF of 23.
The results you are showing in your email also don’t show that you have them allocated to different fleets, but you are scoring as one fleet
If you are using NHC, you need to have all the competitors that you wish to be scored together in the same fleet
So I would suggest you have a fleet named “personal” and move what you have in the fleet to a division column
Looking at your file, there are a few problems. The biggest one is that you seem to be using average lap racing, and average laps are not supported for personal handicaps, as the lap is not transferred from the Sailwave into the spreadsheet
The other issue is that you have recorded elapsed times not in the standard format of minutes and seconds. You’ve just put in one case 7, so it’s taken it as 7 seconds instead of 7:00, which would be seven minutes.
Hope that helps
We could look at possibly supporting average lap racing. I don’t know how much demand there is for that with personal handicaps
Thanks, Jon. Further investigation suggests that the NHC errors were being caused by the seven second entry that should have been seven minutes. I have corrected that and it now behaves. Our timekeeper is recovering from his chastisement.
We solved the lap timing issue by dividing elapsed times by the appropriate number of laps prior to entering the results. Incorporating lap times in NHC would reduce chance of errors by eliminating a step in the process.
Can you clarify this for me. We use NHC and average lap time in internal mode. Should we not be doing this with NHC? Previously it always seemed to work ok.
NHC has no concept of laps; it is not in the specification of NHC. If you use the external/Debug option, you will be able to step through each race and see how the calculations are done. You will see the times that are used. I guess it could be possible to add it, but this is the first time it has really be discussed. I would need some discussion before it was implemented
I am glad I asked because I was going to use it in mixed racing with AVLT. Seemed to work well previously albeit I never picked up on the different laps being an issue.
I wont use it this year now I know. Will come up with some other method to modify high placed finishers for the next race instead. Maybe add laps using the average laptime of laps completed, so everyone sails the same number of laps. Not sure…
