performance numbers

[stunad]

Hello, i am just getting into the thoro-sheets and find them to be a terrific handicapping tool.  I have one question, I do not understand the significance of the small number above the performance rating. For example,25 and the small 2 on the upper right hand side. If a Horse\'s rating is a 25 and another is 25 with the little 2, what is the difference? Thanks a lot, Frank.

The superscript number is in quarters

1 = 1/4
2 = 1/2
3 = 3/4
