Alternate way to calculate betting the pot

[2ndGoat]

I'm aware of the normal way of figuring out a pot sized bet- your raise amount is everything on the table plus the amount you'll have to call in the process of raising.

Here's another way:

3 * (largest bet this round) + (all other money in play, except yours).

Largest bet is in terms of the biggest total wager in front of someone so far on that round, not necessarily the biggest amount bet/raised in one action (in case a bet bet and reraised or some such). This gives the "raise to" amount, the total you'll end up having in play in front of you.

This makes sense, right? In any case I thought it might be helpful to people that have occasion to make the calculation regularly... assuming I haven't fouled up somewhere.

..I also believe raising half the pot works out to 2 x (largest bet on the table) + .5 (all other money in play, except yours).
