I was harvesting under the same conditions and had very little if any coming out of the back of the combine. I ran the rotor between 300 and 320. Wind was at 730 and was running around 4 to 4.5 mph. Was cleaning really well and was only finding a kernel or two on the ground. You might be moving the material a little to fast and not giving it enough time to seperate. Hope this helps
