Mine too..Low hps2
I also dropped Quite a lot on the leaderboard.
And As a result my shares are lower

Do where I was in top 10 I am no at 20 or so.

And there is a big differenws between my miners although hardware is rhe Same.
One has hps of 1500 other 13000 which was the lowesr before the update.

So there is some flakyness at least. If All would be at the samelevel then there wouldnt be a problem.
But as there is difference between the Same hardware it most likely is a big or something somewheew Right?
