No reason to feel badly. I don't think I would have won even with the additional points from Race 10. Your entry was a brave try at the pick 6. There were a lot of long shots hitting at Aqueduct, which made that a difficult pursuit. I am more mad at myself for my ROI entry than my flub in the points contest. If I am not picking horses badly, I am picking races badly.
I usually really handicap 3 or 4 races and invariable pick the one that I think looks easiest which often turns out to be harder than I anticipate and then I miss a race like the feature race on Saturday in which I actually had a good opinion.
I think the lesson from that is to stick with the graded stakes, but I was a bit intimidated by the big field with so many horses that looked like they could hit the board.
