guidelines for postflop raise amounts

[OngBonga]

I tend to click "50% pot" and then adjust accordingly, depending on board texture and villain(s).

I think this is how it works... let's assume the pot is 10bb, and villain bets 6bb. Now it's 16bb, and I click the 50% button. I would effectively first call the 6bb, making the pot 22bb, then raise by half, which is now 11bb, meaning I would raise to 17bb. Villain now faces an 11bb call into a 33bb pot. He has 3:1, so if the flop is wet, or villain tends to call raises too much, or I'm looking to build the pot to get a big stack in by river, I would increase the raise size to decrease his pot odds and/or increase the pot.

However it works on a mathematical level, by clicking 50% I quickly get to an acceptable default raise amount offering 3:1, which is usually adjusted.
