I'd bet that your lack of a muscle up is more about aggressiveness than it is about strength.
I thought I'd lost one too, then got aggressive and knocked out 6 in a row. I didn't do another one that day, but I did them.
Be careful though. Don't want your shoulders and elbows to get ripped up.
Things are looking solid and getting dialed in. And fun too.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
