The problem with this, is that 16 repeats is the AVERAGE in 40 spins.

Obviously there will be more than a couple, but what is the minimum number of repeats in 40 spins, and can we win that way without an insane negative progression?

I was trying to work on a way to win in 37 spins, knowing that there would be 5 repeats minimum, as anything less than that would be an astronomically small chance.
