ive got a s9 13.5 and a ebit e9+ 9.5 running on the same worker in and my invalids are only at .065 % is this the norm?
Do you have a screen shot?
For the S9, the only % is for Hardware Errors, which are different than Stales or Invalid Shares I believe.
Look at the Discarded, Rejected, and Stale columns.
58,453 Accepted
497 Rejected
438,883 Discarded
15 Stale
58453/439395 = 0.133 or around 13%, so around 1 out of 8 are invalid
S9 and S7 both have around these levels for me.
