Is anyone else out there noticing a radical drop in individual hashing rate? BFGminer is reporting that I'm hashing the tail off of my tiny little ANTminer U1's and ASICminer 336MH/s devices typically total output of 6GH/s to 6.5GH/s and Slush is only reporting 3.5GH/s on current round and my 10 round avg is dropping as rounds cook off. Just noticed this as we broke the PH/s for the Pool, and don't understand the relevance? As an undesireable side effect, my payouts are similarly lower (nearly 50% lower), and I can relate that with higher Pool Hash rates, my tiny share is lower proportionally, but not by the nearly 50% as I'm seeing. I'm seeing fewer than .1% rejected shares, and lower than .3% HW errors, so I can't attribute it to anything on my end of the equation. Can anyone please enlighten me?

Late update. Not a pool related issue, but a power starved Antminer U1. Replaced power adapter for USB Hub and all is well in the household once again. Sorry if alarm bells went off for anyone. Once again, it's the newby not properly checking out his own side of the setup thoroughly. But then again, that's how newbies gain experience. Thanks to all for allowing me to resolve issue on my own.
