I'll try with ccminer (downloaded by your tool) although theretically (palgin/truvot) it has lower hashrate or maybe excavator gives fake-hashrate.
Maybe it's the reason. It's worth checking. If I can say somethng that instant changing miners until we don't remove files on folder "Miners" is really strange.
By the way I've prepared a little dark theme for Stylish/Stylus for pool for those who likes dark themes for everything. I know about addons that do this things but they do this in a ugly way.

The Dashboard page has grey text though for the hashrates, can we lighten that up a little?
