I'm taking it slowly, in my case will see if it's just some delayed payout.
I have rented a couple rigs, thus it's easier for me to check rental price vs payout, that's the reason I can give you the 7% figure. So far it's been somewhat profitable to add some rental, with the benefit I can do the math and calcs were always very close to reality by less than 2% error.
Will wait a bit then, I still guess it's a payout delay or some stuck btc somewhere.
