So, assuming 2/3 PSB on the flop and the turn, a good SPR for a top-pair hand is 2.22.

it's a decent starting point if you have no other information. once you know your opponent you can make better estimates of target SPRs.

also, the 2/3 pot bet assumption will skew SPRs down but not as much as basic arithmetic suggest. that's because opponents will call 2/3 pot bets more often, on average, than they will pot-sized bets.

So assuming 10-12BB pot preflop (ie standard raise sizes) with a raise and a single caller, optimal stack size is 22-27BB?

optimal stack size is 22-27bb plus whatever you put in preflop.

that reasoning assumes a tight opponent or a weakish top pair hand. keep in mind that that is the OPTIMUM stack size for commitment - your target SPR - the stack size that makes you the most profit, on average, when you get all-in. you can play for considerably bigger stacks and still make a profit, but when you get all-in with bigger stacks you will face a tougher range of hands and not be ahead as often. eventually the stacks get big enough that if you get all-in you expect to lose money on average. the breakeven point is your max SPR.

the book's much easier to follow. SPR is a complicated subject and hard to present in forum posts.
