1) The negative thing makes the graphs a little tough to read. I know you've talked about changes in the past. Just adding points to every figure eliminates this problem. I'm sure there is a reason you haven't done it, just curious what it is.

2) Why not incorporate today's weight into the figure? For example, a horse last out ran a 2 carrying 120, today is in at 114. Adjust the 2 to reflect what the horse would have run at today's weight. Instead of adjusting evey figure to a standard weight, leave them weight unadjusted in the database then adjust them when they are entered to today's weight. Hope I was clear.
