Anyway I might be wrong, misread

Код:
Use the above if the order in which the code is executed does not matter. You can optimize that too further but I feel that it will reduce the readability of the code.
But still I was wondering since you say (+1), I wondered about the loop that uses i-- which in this case is
Код:
for(new i = GetPlayerPoolSize();--i != -1;) {}
A close inspection on the assembly code will tell you why backward loop is faster than forward loop and why. In a forward loop, you are using an additional variable 'j' which needs to be fetched from memory for every iteration whereas in the backward loop you needn't. For the same reason , '--i != -1' is faster than 'i != -1;i--' (you are decrementing & checking the falsity of the condition at one variable fetch).
