I've pushed a few thousands hands of SSS around and I'm kind of curious why the rules tell you to wait until you get to 15BB to rebuy.
It seems like topping off just after the blinds would be slightly more effective otherwise you are giving up 7.5% of your fold equity every time the blinds come around. During that last round you are at a fairly crippling 22.5% loss!
It is more correct to top-off or is there something I haven't considered? I know when I finally get those pocket aces I'd rather be looking at a $2 stack than a $1.55.
