well it's obviously a beta idea being tested.

But it seems to work a bit as my minions switched from wdc to mnc at least once, as I have a balance of both on my account now. As a test I stopped/started my stratum proxy server and it looks like they're still working on mnc.

edit: nvm the stats on the page seem a little lagged, they're working on wdc now.

Maybe as a workaround I'll just throw a script into a cronjob to have my stratum proxy restart every hour.
