Any antminer d3 users notice really poor performance compared to expected results? My d3 says it's running at 19.3, which I usually estimate as 18 on pool, but even with that estimate on whattomine, I never hit it. It's almost always much less, not the usual less and more like you'd think with luck variability. My ether GPU mining rigs are usually spot-on or higher if I estimate about 1 lower (they do 29.3, so I use 28 as the estimate). Regretting that d3 purchase. What a POS, even though DASH is a great coin.
