juts a quick follow up...
within 15 minutes of me posting the message above that I had switched one of my machines to Mona - Mona's network Hash went from 94 MH/s to 119 MH/s - the highest it has ever been.
well sorry to report... I've switched again and left Mona for a higher paying coin if you're watching and I know you are...

So are you saying that you have Smarterhash tied into your mining pools? So that it automatically switches your miners for you?
