Strange behavior when changing the "-i" parameter
I have experimented with the "-i" parameter on some algorithms. If you change this parameter on the KlausT miner, in the file NemosMiner\Miners\ccminerKlausT.ps1, the application after restart downloads the miner again and it takes another stop / start to start the bench.
At the same time, if you change the "-i" parameter on some algo for Trex miner, the application does not download it again and immediately starts the bench.
Also about speed, with a default value of -i 12.5 on the yescrypt algo, the speed on my system (1080ti) is 40MH, with a value of -i 14.5 - 55MH. Almost the same with yescryptR8 - default -i 12.5 40MH, -i 14.5 57MH.  
I also noticed that if I remove the -i parameter at all, the miner himself will choose the best value. When I remove this parameter, I get the best speeds. I think this applies to all miners.
