I am glad that some people see their income has gone up (previous post a while ago on this page)...but in my case,
while my speeds are pretty consistent on two of my miners at 385 Mh/s and 285 Mh/s, respectively, btcguild often records them much much lower...my income has actually gone DOWN today...from average 0.0214 for 1.183 Gh/s (both 96 hr averages) to 0.0173 for 1.183 Gh/s today.

Why?
