I'm having very spotty runs with Mining Pool Hub.  I'm buying hash power from NiceHash.  I've had some runs for ETH where I've made 8-10% and I've had a few where I lost a few % and I had one where I lost more than 10%.  I'm currently doing two orders for Zcash and despite running with a very low price it looks like I'm going to lose maybe 15-25%.   The only thing that was really different with my huge loss runs were I ran at a high speed limit.  Not sure if that's a problem or not.

And why does the Sharerate meter on MPH max out at 1?
