I am curious, perfectionists are all insane (and I am one of them).
As far as I understand it, the number of edits has little to do with post payouts. The payouts declined in the last months due to the falling price of Steem.

so far I have not had seen any downside to editing posts, other than using up bandwidth, which you only have a limited supply of per day. So try to make less but larger edits at once.
