Formula for QB Rating

[Andrew]

Does anybody know the formula the game uses for QB Rating?

I'm working on some things for the website and used the formula here:

http://en.wikipedia.org/wiki/Passer_rating

but the results don't match those in game. I've looked at various calculators, but can't find the formula that the game uses.

Actually, I'm fairly certain that it uses the NFL formula, although there are some unusual roundings at times that might throw the calculations off by .1 or so. I'd just use the NFL formula.

Thats what I thought, but it was off by 10. I then plugged in the formula on ESPN and it was also off. I must be doing something wrong in my math somewhere.

If you're so smart, tell me where I screwed up :D

hehe thanks

That didn't actually work, did it?

[Andrew]

The code I originally posted worked already. I was just giving diesel a hard time.
