My rig is taking longer to pay, did the same thing happen to someone?

months before December, it took 3 days to pay 100% of what was mined, but little by little it took another day, until now it takes 6 days, to mine the same. I thought it could be the plates, but nothing has changed, neither its configuration nor its oc. what we have done is update the hiveos version. will that???

Man you need to read more. Whats the amount you mine, is it the same ?
