Is it normal that I get in and out of the payout queue? At various points it shows a remaining 0.000000BTC remaining to get in the payout queue and sometimes it shows an XX amount of block to get my payout. It already went back and forth a few times so far.
Yes, normal, I've had this several times.
It's where the estimate of your next payment varies slightly as time goes on and you are on the edge of the block, as I understand it.
Not to worry, if you don't get paid this block then you are well positioned to be paid, almost certainly, next block, assuming no untoward events, such as an orphan.
