The numbers we've been reporting are on the LSDAS report, swifty. It gives you the mean, your GPA percentile (for your school), and a histogram of grades and LSAT scores from your school. This isn't a fair sample. It only represents people who apply to law school. Apparently, applicants are above average.
For example
this site lists the means of many schools tracked through year (scroll down). It says my school, the University of Utah, is at about 3.04. This is much lower that the LSAC figure of 3.33.
It appears that inflation is worse at private schools. Stanford, for example, has an average of 3.44! Therefore, saying, "but I went to Chicago [or whatever]" shouldn't help people with low GPAs. ...In an ideal world.
You're also right about Sacramento, swifty. According to the link, your school has a mean of about
2.86 although the national average is 3.09. And that's for your school overall. I bet your department might be much worse. The other CSUs listed are about 3.0. You just have bad luck.
I really think more schools should be like this, but it's unfair when so many give out easy 'A's.
School mean GPA - 3.37
School mean LSAT - 163
My stats - 3.44 (55%) / 160 (re-taking in October)
So the question is, are adcoms going to look at my 3.44 and say "geez, that's on the lower end in general" or say "hmm, well the LSAT mean is high so there's stiff competition GPA-wise at her school.." or something like that...
Damn LSAT. 
Your school has an LSAT mean of 163? Where do you go?
