I am familiar with the correlation charts that are floating around out there, but thought that they were only valid for calculating IQ from college admission test scores that are at least 15 years old or so. I believe that once the SAT was re-centered in 1995, it was no longer possible to use it as an effective measure of IQ (and therefore is no longer an appropriate tool for determining LOG). I know that Mensa doesn't accept SAT/ACT scores from after '95 for admission purposes, for that very reason. The new version of these tests just don't lend themselves to IQ correlation.
