I'm having trouble mining X11 by auto-switching multi-algorithm. In last 3H I have mine with two miners PC1 and PC2. PC1 is viewed by the pool correctly but PC2 is reported only hashing 12.3 Mh/s but sgminer is reporting 23.9 Mh/s and the same CGWatcher.
Where are the others 11.6 Mh/s.  
My btc address is 1KNQLwC1cEY4P3MjvdkijuDeZaEdnYVghx.
At the moment mining only with PC2 machine to check the problem.
