Although the srbminer was working usper stable with my Vega rigs and gave me amazing nominal hashrate, my adventure with srbminer comes to the end

After a lot of monitoring I figured out that srbminer and cast.xmr give me much less real hashrate than the miner hashrate. I have tried several pools and difference goes as much as 20%. I don't know why, one of the rigs is correct (12KH/s reported by miner and pool) and others vary from 11.5 to even 10KH/s real hashrate. I have 0 invalid shares, everything works beautiful, but my hashes are missing.

Although XMR STAK gives me less hashrate, it is spot on with what the pool reports. I have read few pages ago that older versions of srbminer do not have this issue, but I can't find them online anymore.

After long time, back to where I started, hello XMR STAK, sorry doc, your miner is awesome but difference is too high for me.
