>>32007873it is useful
you know that fire spin tends towards 100 more than it tends towards 150
its not complicated
the sum of an infinite geometric series is a great and fast way to eyeball an expected result for these types of moves
it doesnt matter at all if it wont hit 120, the entire point is to know where your result is PROBABLE to land.
saying that knowing the expected value tends towards 120 is useless is tantamount to saying "knowing that it was a 80% chance to land didnt help me because I didn't land on it"
