Points and Scoring Question

[MightyDuc Racing]

How does the performance index work?  Can anybody please explain the formula to me so I can figure mine out.  Thanks!

It seems to be:

[(T-A)/T]*1000 = performance index

where T = the total number of people in your races - including you.
         A = the total number of people that finished ahead of you.

Makes sense...thanks!
