What would cause this weird bearing wear?

never assume anything the last couple of rebuilt cranks I got were way off ,one bent with .008 run out on the center main (they ground a bent steel crank) ,the other ground too much on the mains . they came up with .033 main bearing set. to get .0025 .(someone grinding crank didn't have his glasses on that day)clearance on the main bearing. always check bearing clearance and straightness .
also end play.
