I usually look at available stack depth and see whether it looks to me like set prevention with AA--at least without having watched your betting style for a while.
So, with 200 stack depth and a 7 raise, I'll be more likely to attach a wider range to the 29 raise than to the 36. If it's >40, that will look a lot to me like AK or QQ, possibly even TT-JJ and AQ. 29 looks to me like QQ-AA normally. 36 looks a lot like AA with KK also in there somewhere. But I'm also coming from FR.
