The bot at https://mrgris.com/projects/minesweepr/ does these calculations, and has a winrate of 37.8% on expert. I don't know what a more naive bot would achieve.

Is this better compared to an actual expert human?

		I think the human experts mostly care about speed rather than their average solve percentage. If they're forced to guess then they can just restart if they get it wrong.
