if you mean allin preflop, i think you should go only with monsters and just one player against sometimes 2
but if you mean allin postflop, the number could be higher maybe over 10 times in mtt where you need at least 200 hands to reach final table
i think every mtt has its own story so don`t like to go that way, i mean when i start to play i liked milestones, so i said i had to see 15 of the first 50 flops, 10 of the next 50, and so on, and went like i had to have that number of chips after 30 min, and after 1h and so on,
but then i realised that one can not push the things like that because one put other variables in play which destroy the game, so now my view is slightly different, i don`t care about numbers or stats that don`t impact the table where i`m playing, for instance what`s the difference between seeing 2 flops in a 100 hands or seeing it 50 times if you have the same amount of chips?
yesterday i was plpaying a 90 players mtt, and i registered but had to go for a while, so when i arrived there were played like 50 hands, two hands later i got AKs and somebody with a bigger stack shove and so i did and a third villain did as well, i won, i tripled, no more action for me until i got QQ ten hands later, 4 limpers, i put 8bb one of the limpers went allin i called and won, tripled again, no more action for me for a long time, but when i realised there were remaining just 15 players and i was 3rd, so it gave me a great lesson about patience in poker pays off, so don`t force things just let them be
