Than in single table tourneys?
I just thought in MTT's you get put in dangerous situations earlier on (such as all in decisions) so you would need more luck in those to survive. Am I wrong?
More luck, or more skill? Playing in a live MTT you can use the large amount of players, and live read &
tells to make plays out of the ordinary to net you extra chips compared to your opponents at the table.
I figure it like this though, even with your calculated risks you are at best sometimes a 90% or 95% favorite. Sometimes these risks are for all of your chips, if you can reduce the amount of risk ( don't put all of your chips in the middle unless you already are 100% or have the nuts ) you can avoid having to rely on pure luck. That being said...
A sit & go tournament could be getting all in with a 52% edge more than once, maybe 6-10 times or more. Being in an MTT this number is usually much higher since, through acquiring chips you will be put in even more situations where you are putting all of your chips at risk, and sometimes with a lower % compared to a sit & go. Potentially you could run hot and get very good cards, reducing your opponents %, and raising your % in each situation. If a sit and go is flipping a coin 5 times, and if you got heads 5 times you won. A multi table tournament would be like flipping a coin 25 times, and getting heads 19/25 of those times. You need to end up on the positive side obviously, more times than not to eventually capture all of your opponents chips. An MTT just forces you into more of those situations, over a longer amount of time.
