Hi, Sweetie!
What you're seeing are estimates of time remaining in a wash cycle...

It's actually a little bit like the bitcoin time-chain, dependent upon events in the real world. In the case of a clothes washer, there are physical variables such as load size, spin re-balancing, water temperature and flow rate, and etc.
With bitcoin, it's "When will a miner get lucky?."π€π§π And we all rejoice when it's some poor, solo miner, don't we?π«ππ»πππ€πππ
