Haven't paid attention to the total rate of the pool during the slowdowns but this morning it was already slow when I woke up (only making .0011 per hour instead of the .0015 I can get with 5G and this 65Mil difficulty) so I switched over to BTC guild for the day and every time I've checked in its shown 5000-5100MH/s and the number of shares and earnings back up these numbers.
I'm going to switch it back to 50btc and see what it does.
