Here's something you might be overlooking fatb. A player who has a 3b % of say 6% is 3betting on average 6%. But that doesn't take into account the situation, such as position, player, etc. A good player that is 3betting light (as 6% would dictate) is gonna be doing so when a good situation arises. That means they are gonna be 3betting less from EP/MP than from LP, and they are gonna be 3betting players who open in MP/LP, more often than players who open from EP. Therfore, you need to factor in position when you are looking at a 3b range for them. If it says they are 3betting 6% and they are UTG+1 3betting an UTG open, it will be much less than 6%. Same goes for if they are on the BU 3betting an UTG open. It will be less than they would 3b a CO open.

Also while pokerstoves 6% range is the top 6% of hands, it generally isn't a good indicator of the hands that players are 3betting with. For instance, as we know from spoons "Hand Combos" thread, it is better to 3b a hand like A4s than a hand like 88, for obvious blocker reasons. So by just plugging 6% into pokerstove you will generally get a screwed up range imo. You should weight their range more towards hands like Axs, suited gappers, etc (aka hands you would consider C range hands), if you suspect they are 3betting light.
