They did "re-normalize" the SAT a few years ago, to make up for the fact that the average was consistently sliding.
Don't know about the ACT.
I'd like to see the projected "G" trend.

You have it backwards. The average SAT score has been RISING and perfect scores and 1500+/2300+ scores are getting more common. The test was recentered in 1994 because the average score had risen above what it was intended to be (1000). As of today the theoretical average should be 1000, but its slightly higher (around 1030, I believe).
SAT renormalized at least twice and recently revamped. No longer standard, no longer 'aptitude' and no longer comparable.
