I don't think anyone really knows yet, but I can give you an estimate of what I do.
vs. someone opening 50% (typical button)... 22+,A2s+,K2s+,Q2s+,J4s+,T4s+,95s+,84s+,74s+,64s+,5 3s+,A2o+,K2o+,Q5o+,J6o+,T6o+,96o+,86o+,75o+,64o+,5 4o
vs. a 17-18% UTG opener... 22+,A2s+,K2s+,Q5s+,J7s+,T7s+,97s+,86s+,75s+,64s+,5 4s,A2o+,K7o+,Q8o+,J8o+,T8o+,98o,87o
Everything else, somewhere in between.
And multiway, I just always call at least 22+,A2s+,K2s+,Q2s+,J2s+,T2s+,92s+,82s+,72s+,62s+,5 2s+,42s+,32s,A2o+,K9o+,Q9o+,J9o+,T9o,98o,87o,76o,6 5o,54o (any 2 suited) and add lots more offsuit stuff if it's near the button or they are super loose.
