I assume this is going to be moved into the poker section(s), but I'll go ahead and post.
The way you broke it up seems a little odd. But you have to think, 3-4x is just enough to get the bad hands out and the good hands some money into the pot. I actually love the 4x, it's probably my main option of a raise. As far as the pot odds
and such goes, you shouldn't be calling 4x raises with ungodly terrible hands so most of the time it's just not the right flop. I know when I'm calling nice-sized raises, I've got a pocket pair, high cards, or suited connectors. This is mostly when I'm playing tight in a tournament I actually care to win. I think things get different working with big stacks. Depending on the stack size, I'd maximize my raises to 6-8x. If I'm holding a stack of 242,000, with the blinds at 2000/4000, I'd probably bet around 32,000, which is an 8x.
