Nope, on 144,5. But it still fluctuates a lot, even on the pool side. So have a look into it. The EWBF is more stable, but GMiner gives me more, almost 10% more. So you must find a solution to these random drops. And I'm not the only one with these issues.
Could you show hash rate chart from pool?
I guess you have hash rate drop every 100 minutes, remember miner mine for 2 minutes on dev fee pool every 100 minutes.
