I have also noticed these strange issues. Although there is a constant high hashrate on the console, I see there is lot of variance on the pool site hashrate and they are lower. Sometimes for a short period it peaks and is increased but, for a short period. This was observed consistently across several pools. I have been using Bminer for a while however, with these observations and the dev not really addressing the issue that is a concern.
I will be returning back to the more obvious and consistent DSTM.
This is exactly what I experienced and exactly what I did, back on DSTM hashing away,
I really liked the interface of Bminer's stats, telling me I was getting more, I simply would like to experience those actual stats, I feel the GUI was giving false readings at this point...
Same. Back on dstm unless issues are addressed. Dev seems to have ZERO interest in doing so, so he will not get my 2%.
