Sailwave calculates RDGa according to what is stated in RRS A9 (a) Guidance on Redress.
"points equal to the … average of her points in all the races in the series except the race in question.
So, Sailwave includes discard points when calculating RDGa.
Fleet members have noted that a number of international classes exclude discard points before calculating RDGa. I don’t see this documented anyplace formally by those classes, so it must be a convention followed by their juries.
Assuming that you want to exclude discard points before calculating RDGa, can you set up Sailwave to score the series automatically?
NB: One member of our local RC fleet sits out each race to act as PRO. We score them RDGa for that race. Over 12 races for a day, that means calculating RDGa 12 times, plus any “real” RDGa situations. Manually calculating RDG for the 12 plus instances certainly is an option, but one I was hoping to avoid.
Hi Hank,
Please could you give links to ‘…number of international classes exclude discard points before calculating RDGa’?
The problem comes when the RDGa score could end up being the discarded race or one of the discarded races, you end up in an impossible situation.
In Sailwave you can set-up different RDGa codes that calculate the average based on the races selected for that code. This might be what fleet members are seeing.
I look forward to more information.
Kind regards,
Huw
Hello HuW,
Thanks for your quick response.
A top sailor told me the Etchells and J/70 classes have always excluded discard from their RDG calculations. I looked at numerous NOR and SI documents but found no mention of the RDG policy.
So, my information is anecdotal. I will try do provide some actual evidence and share it with you
I can certainly see how the impossible situation develops.
I’m not sure setting up different RDG codes will save me, as, in the RC case. I think that means I would have to have a separate code for each race.
Cheers, Hank

Hi Hank,
Thank you for your reply.

I agree 
FYI - I have just looked at the 2025 Etchells Worlds results (2025 International Etchells World Championships)
These results at least are not excluding the discard/drop to calculate RDGa as can be confirmed when you add up the scores and divide by the number of races as seen in the following screen grab which highlights two boats who have RDG.
I hope that is helpful. I appreciate the Etchells class may have done things differently in the past. If there are events who have scored in the manner annecdotal evidence suggests, I would be very surprised if this was not in the NoR as it could affect a competitor decision to enter or not.
Kind regards,
Huw
Hello again Huw,
Boy were you on the case. I’ll try to find a J/70 instance to show they calculate RDG with discards included,
just as you found for the Etchells.
Thanks.
Cheers, Hank

Hello Huw,
Scanning all the J/70 results posted on YachtScoring I see no instances of RDG.
Your Etchells sample ready brings the point home though – redress should be calculated with discards included.
On another good note, scoring codes can be set up to average all non-discardable results.
So, defining the code OOD to average that way and use a value of zero
solves my thumb-yachting race committee dilemma.
Cheers, Hank
