5-handed stats compared to 6-handed?

[TheGrinder]

How should your stats change if you play 5-handed short limit compared to 6-handed? VPIP should definitely be higher, because there is no 6-handed UTG position, now UTG is actually UTG+1. If you play 6 max and have 24 VPIP, what should it be in 5 max? Should "attempt to steal" in PokerTracker be smaller? I have it 36 in 6max and 28 in 5max, because I feel that people call more in blind positions in 5 max and don't believe you have anything special. On the other hand, if people call more and don't believe you, should you play tighter in 5 max UTG than in 6 max UTG+1, although these positions are actually the same. What about other stats?
