I'm looking at my stats on ckpool for an underclocked s7 at 2.86 Th/s. It has been running about 12 hours and I wanted to know if my invalids are reasonable. It says stale: 28,290/10 ; duplicate: 2,829/1. For a total invalid rate of 0.206%. I think this is reasonable but if anyone can confirm I would appreciate it. The overall pool rate for invalids is higher.
