The thing about the main (and really all tournaments but its magnified in the main) is that your % chance to reach the money is not that relevant of a number, its your chance to actually win the tournament. People that are optimizing for trying to cash in general are less likely to be able to win.
Funny story from main this year, post money bubble quiet guy at our table has played 0 hands in 6 hours, quietly blinding out and stalling a little all the time. He's very clearly inexperienced with the chips. Finally he is quite short and decides to announce to us all "its been super fun playing with you guys all day, I won a bar league and all my friends back home have a piece of me here so sorry I have been slow I'm just gonna try to make a few more pay jumps". Nicest guy in the world and eventually got it in for like 4 bb and busted. The main is full of guys like this. He optimized for cashing, reached his goal, but has basically 0% chance to ever win, or even reach the final table, where all the $ is.
Anyway no point to this other than when playing a tournament you should usually try to win it, and if you are a halfway decent NLH player you should always always always play the main
