The coin has to land sometime and at any given time it has spent as much or more time facing the way up it started, so it has more opportunities to land that way up. The fewer times it spins, the more pronounced the effect.
I think that’s only relevant for coin flips which last for less than half a spin. Probably much less, considering momentum.
So maybe this means that 0.8% of all coin flips make less than half a flip. They basically just throw the coin up, without changing it’s rotation?
I don’t see how the number of times it spins could have any effect, as 1 spin is equal to 3 spins, or 101 and 57895.
