The first time in a match it does catch me off guard sometimes, but yes after enough time spend as survivor hitting that skillcheck ain't that hard. It does prevent gen tapping to stop it regressing, although I almost never use it.

I do have nice overcharge memories tho; I remember a hilarious match when I was still in low ranks with a trapper that kept coming back kicking the gen and me hiding behind a hook in the corn like 5m away. He never caught on I blame corn blindness combined with confusion because I hit the overcharge skillcheck like 5+ times in a row. And I still have a clip somewhere of me hitting an insane backwards mini skillcheck caused by the doctor's impossible skillcheck build, that's really satisfying. So I would say it's situational/ build dependant and works best in lower ranks.
