How long do the tournaments usually last?
Well, lots of variables Like Players number They play stile Tipe of tournament ecetera
One of the point made by @daizoh , 5 month ago, for a different topic, I just copy here, what is just a drop in the sea. But give you the idea how difficult ( and imposible) to answear to your question.
"While it is obviously true that the tourney time increases with the field size, it does not increase dramatically. According to homepokertourney.com, a typical tournament is expected to end with the killer blinds, that is, when the sum of blinds and antes at heads-up are anywhere between 5% and 10% of the total chips in play.
After observing a small sample of MTTs with various structures and number of entrants at replaypoker.com, I would say the 5% rule is a close upper bound for the killer blinds on this site. Also, it looks like the observed ending level for N players is not too far from 2log2(N), at least on the sample I observed, that is: * for about 32 players= Level #10= 2log2(32)= 25, * for up to 64 players= Level #12= 2log2(64)= 26, * for up to 128 players= Level #14= 2log2(128)= 27, * for up to 256 players= Level #16= 2log2(256)= 2*8. The logarithmic function is a very slow increasing function, as it increases only by 1 when the argument is doubling.
You should always prepare yourself for a field of about 100 players and an expected conclusion at level #13, with usual range from 50 to 150 players (from level #11 to Level #15). This way, your error for the estimate of the killer level should usually be about -/+2 levels, that is about: * -/+12 minutes for 6 min-long levels, * -/+16 minutes for 8 min-long levels, * -/+20 minutes for 10 min-long levels. (However Omaha hi/lo is prolly more resilient to killer blinds than Holdem and Omaha due to frequent hi/lo splits in heads-up…)
