This is actually more complicated than many assume and I believe has been discussed at some length on this forum in the past.

I'll try to find the thread. Hopefully someone else beats me to it.

As far as my personal feeling, from a strictly naive mathematical perspective, it's 1.844 as opposed to 1 ev with the double up, so you'd need

1.844*.545>1

or about 54.5% to be on the edge of profitable

Where it gets more complicated is the fact that your average time/tourney goes down by a lot if you could do this all the time (which in a way you can) and for some (especially skilled big stack players) X might be less than the math alone indicates.

But not a lot less

I may be wrong. Very quick guess
