hayatekirino: i don't understand what exactly want to tell.
For example someones cold call is 10%. you mean he calls with PP and SC and Aces and and... ;
if he has 4% then i must worry more for a set on flop?
Google "Pokerstrategy.com equilab", and d/l the program, it's free. Play around with it and you can see that % of hands small PP are, 4-5%. Then add in decent SC, Axs, broadways that people might call with (KTs, KJo, etc), and you then see the % goes up from 4 to 10 or more depending on how many hands you add to the range. It will let you visually see what kinds of hands someone who cold calls 10% might have, vs 4%.
I can't tell you someone who calls 10% their exact range, maybe they call J9s and 87o, or not J9s but 43s instead, who knows. But it lets you see you are up against a wide variety of hands. But a 5% call is perhaps almost always just PP and good Axs/AQo.
