We have fixed a duplicate share bug in multicard rigs on the hiveon pool and possible other ethereum 1.0 stratum pools. The ~2% rejected shares are now ~0% in version 1.26 and this will improve the poolside speed..
Happy to hear, I had pool side speed issues on hiveon but good results on miningpoolhub. Flexpool seemed to have a lower reported rate like hiveon, so looking forward to testing v1.26.
I've been using your miners since you used to do specialized paid miners, I think I purchased a skunkhash miner from you so I know you do good work.
