This topic did not draw a lot of attention because we all know the Dosage Index went out the window too long ago to remember. Since I join the rest of the room in considering Dosage a non-factor, I still wanted to respect a fellow TG'er who put a fair amount of time and effort into his theory.
The only category I had any interest in was the Fast Contender with a Dosage of < 3.50.
This chart played a mild factor in my setting aside a small "basket" of wagers using as a secondary factor in addition to the main factor being JB's numbers on the horse.
The result was actually very profitable for me and something I'll consider doing in future Derby's. But not as a primary handicapping factor.
Using the mentioned category I thought it showed the most promise.
There wound up being 4 horses that met that criteria. ( Fast horse, TG figure of 3 or better and < 15/1 odds).
Up until they sprung the gate and Candy Boy dove from 16/1 down to 9/1 there were only 3 horses that met this criteria.
California Chrome, Danza, and Wicked Strong who were of course the 3 betting favorites. Had Candy boy remained at 16/1 he wasn't in this category.
Then I looked and the forward moving patterns of horses in the remaining field that had a TG of 3 or less and landed on Curve. It did prove to be a pretty good tool in eliminating 10 horses in the field.
I wound up with Cal Chrome on the top of 6 tickets and in the place hole 19 times. I played Curve on top 4 times and 8 times in the place hole. I also had Danza on 11 tickets spread across the super board, and Wicked Strong 7 times in various spots.
Long story short, I got lucky but not real lucky. I had Wicked in the 4 hole on 2 supers, but Samraat who lost by a nose to Wicked in the 4 hole 6 times at twice the odds.
Moral of my story is I'll use this as a small contributing factor in the future. But, without solid, realistic TG numbers to rely on it does no good.
Different strokes for different strokes here.
