I can confirm seeing shares from every 4 of your rigs, you're the fastest miner on the pool currently

I'm not sure why it is only displaying 1.4 mh/s if every of your rig has that power, but i've just checked and my hashrate is also displayed a little too low, i'll fix that as soon as I've got a little spare time, it has no impact for your payouts, as all miners currently are displayed a bit slower than they are, so don't worry, its just an optical issue.
