I guess i wouldnt look at a static number here. In general a lot of factors come into account about flatting-/squeezingtendencies, RFI%, positions, cbet% and so on.
Without further infos i would just take a look at hands that have reverse implied odds and cut them out. There is some sweet-looking hands that are risky to play MW, esp oop:
KJo/Q9s/QTo/A2o-AJo....
While there is some hands that become quite interesting (cause they can make strong hands without too much risk of getting dominated): AXs, middleing SC or KXs
With these hands we try to hit gin or simply let them go postflop.
Thats often more complicated with QTo at Q749J :/
