I couldn't help noticing that Thoro-Graph has started to post the Horses Weight at race day between the running lines from some tracks, I saw this when studying the form from Santa Anita on saturday.

I was curious as to how you guys factor this into your handicapping. When is it relevant, when is it not relevant, is it the difference from raceday to raceday that interests you the most or do we believe in an "ideal weight" that correlates with top form and that patterns could be identified with TG figures, simply put -
what are the working hypotheses out there?
