I’ve posted my detailed weight breakdown in the original post. Feel free to comment. 
Looks pretty cool Shanthi! Can’t wait to see what happens once weights are in place actually, should be real interesting…
Everything looks great but I have one small input. The weights seem to be overly large for each category. For example, many a maiden racer simply could not carry and impost of 122lbs. It’s a huge amount. If my memory is correct, the largest weight a horse ever carried was in the area of 136lbs. That was in a stakes handicap, I believe. The point is, if these are the base weights that will be used for the new system and they haven’t been modified, I would suggest to lower them.
Maidens carry exactly around that weight, at Philly park today in the first race, a maiden claimer for three-years olds, all the horses were carrying 119-121 lbs.
140lbs is a bit on the high side, but it is also the limit so I imagine only the ‘greats’ would be running with this weight.
The weight for handicap races ranges from 108-150lbs. Only horses who are odds-on favorites would carry anything close to 150lbs, however.
The weight that horses can carry and still run at 100% is 115-140lbs.
