I take it that's for 180s and not for 45s? I would have thought the heaviest ICM factors in 45s would have been 8-handed?

for 45s, it is 8th that is the heaviest. But what most people don't realize is that ICM factors in 45s are much, much stronger than a 180. There are several spots in a 45 man that are more similar to a 18 man bubble than anything else and for several places. A lot of people think you can just load up both 45s and 180s together, but they are not remotely the same, it's a whole different game at the FT.

+1 to the above. With the exception that 3-handed the situation is reversed, there's actually more ICM pressure in the 180 than the 45 man.

I'm interested that you say you shouldn't load them up together. I think even if you play a bunch of the same size tournaments you are always at different points in them so it's tricky whatever anyway.

Yeah but the best SNG players spend hundreds of hours studying ICM for a specific format to be truly knowledgeable about it. After playing 9s and 18s at low stakes and doing fairly well, it wasn't until I played 6 max at a very high level before I knew how bad my ICM at 9s and 18s was. When I tried to load them together I found I was making huge mistakes in the other games because I didn't know ICM in them nearly as well. If you have put the work into learning the ICM of both games equally, then sure you can do it, but you can't just say "Well, I'm crushing 180s, that must mean I'm good at 45s too" because they are radically different at the FT. Now, as a whole, I believe that 45s are some of the softest SNGs because their low volume doesn't attract many dedicated regs, so that helps somewhat, but if you're winning at 45s and 180s at the same time, but you've only ever studied 180s, it's because you're playing in absurdly soft fields, not because you're actually good at 45s.
