Posting 10+ shorts a day?

Hey guys,

So this is not for the faint-hearted but I've been posting 10 shorts on Youtube a day and doing pretty good, you can see from the screenshot.

However, I'm trying to post 20 shorts a day to test the format, and for the fourth time this has just happened where short number 11 to 20 die at 5-40 views and never pickup, even though the shorts are the same quality if not better than the previous ones.

I know youtube doesn't have a cap on shorts and some accounts post 100 a day, but what could be happening? who to ask?
