Always have three and have always placed if I have had to use them all. I may use them all, but I find a way to (at min) break even one way or another. I think I have gone through all three once with no return, but that was in July when
wsop was going on and everyone was super fit and ‘wise to the books’, even at the rec games. Playing the usual recreational home game hero’s, I always place if I ever spend three lol
Most games, I just spend one (or none) and use half for an add-on during break, even if I am the largest stack at add-on break time.
The reason I use three is because I am about 90% certain that if I bust out, it ‘isn’t’ a mistake I made, but just the luck of the cards. Sometimes though, you just get a cold deck and at the same time play against great players… but that is very rare in Rec games.
In short, being cool headed, persistent and aggressive, I almost always get my money back, so that’s why I have three. I can’t say I’ll ever use a 4th, if I can’t get there by three, I just wait for a new tourney lol
I can elaborate on why I will gladly spend three at any tourney but in short it comes down to it is worth it to rebuy considering the time and effort it takes to allocate time and money to get the tournament to begin with. Just how I think of it, leaving after a single buy-in/bust out leaves me feeling like, why did I spend all this energy to get prepared and be here only to leave if I bust out once. So I give myself three chances irregardless, my mind already has the money spent as just part of the game

ALSO: I would highly advise not doing more than 2 rebuys if the automatic shuffler isn’t working lol I saw AA 5 out of 8
hands by hand shuffle….not saying it was intentional at all, but I just don’t rebuy or feel confident to rebuy unless the card shuffling machine is working/present.
