My latest magic poker number

I've always liked coming up with magic poker numbers. What do I mean by a magic poker number? It's a threshold of some kind which guarantees you poker success if you can achieve it. The first magic poker number I came up with was the golden ratio. I figured out early on that if I could achieve twice as many winning sessions as losing ones, I was in the clover. My latest magic poker number is what I'm calling the golden 6-max sit and go duration. It's the minimum number of hands you must play at a 6-max sit and go table in order to be guaranteed of making the money. Pulling a number out of a hat, I came up with 90. Checking the history, of the 34 times I've played at least 90 hands, I've only missed the money three times.
