This chart has you as right: http://www.iqcomparisonsite.com/iqtable.aspx
However, Mensa apparently has different cutlines for different tests, ranging from 132 up to 148.
I think the reason for that is the difference between scoring models that use 24 point standard deviation versus the more common fifteen. If I'm not mistaken, they admit those two standard deviations above the mean, or the top two percent.
