When I was working I worked with an electrical discharge machine, EDM, for creating forge die cavities. The whole process was eroding the die surface with minute electrical discharges. Every discharge created a very symmetrical crater that looked like a hemisphere. I don't see that on the moon. The majority of craters have flat bottoms with a mud ball dot in the middle of them. I am not disagreeing but I do know what a discharge crater looks like.
