Roger, Good job on taking the time to figure all this out.
FYI... I am know handicap expert. I have never used the program or done scoring. I may be wrong in understanding how you apply the adjustments. Here is my question. How do you come up with 66.29 from DP-N 69.1 - JU .995 - MN .995 - BM .995 - L3 .974 = DP-N 66.29 ? I come up with DP-N 69.1-MN .995-BM .995-L3 .974=DP-N 66.136 and when you add in the jib hit I get DP-N 69.1-JU .995-MN .995-BM -.995-L3 .974=65.141. Is this correct?

We use Portsmouth ratings so we can race our (sometimes very) different boats. The Portsmouth ratings are indeed unlikely to be accurate after 2 modifications, and I do not support using 3 or 4 mods. Perhaps SCHRS system can provide more accurate ratings, ... someday. That being said, Scott is an excellent sailor, and every time I have competed against him, he made fewer mistakes than I did, had a well-prepared boat that didn't break down, and sailed his boat to its fullest potential. I suspect he comes out on top of the ratings in most scenarios, and I will continue to try to get to the line first, on whatever boat I bring.

The issue that I have received so many inquiries on.. is, Scott Tuma's rating on the P18-2. So let me address this now. His rating was derived from the table of DP-N modifications in the US sailing Portsmouth handbook along with the table of pre-calculated classes.. Keep in mind that once more than two modifiers are combined, the ratings become unstable. You can find that statement on page 19 of the handbook. (top of the page) I had a long conversation with Nathan Titcomb Offshore Director for US Sailing. For those of you who do not know, the offshore department is where ratings are produced for sailboat races. I explained to him the situation and what I knew to be fact about the modifications to Frankenkitty. In his opinion, I applied the rating for Scott appropriately if not punitively. At Nathan Titcomb's recommendation, I am putting together a group of Certified Race Officials to fully measure Scott's boat. Not only is Scott willing to let us measure the boat, he welcomes it. He also stands by his offer to switch boats with anyone. I also plan on getting the folks over at SCHRS involved as well. So now back to the scoring on Wayward Winds. So in preparation for this message. I re-scored the race and posted it to the sailwave results folder. I am also adding a screenshot because the sailwave site has been kinda fluky lately. This time I also added a larger jib modification as well. So here is how this works. DP-N 69.1 - JU .995 - MN .995 - BM .995 - L3 .974 = DP-N 66.29. This is one more modifier than what I told Nathan Titcomb about. . THE FINAL STANDINGS REMAIN THE SAME EVEN WITH THE ADDITIONAL MODIFIER AND REDUCED DP-N.
