I have an I-roast and many times when I finish my roast I still have chaff in the crack (like an earlier post). The most recent roast I was at first crack in about five minutes and second crack at 8 and a half minutes. I am wondering if the beans are not expanding enough during the roasting process. The highest temp I seem to hit is 366 degrees. Any thoughts or advice?

This is what I am roasting - Panama Boquete -Lerida Estate Peaberry. I don't think the temp is bean temp, but the hot air temp being pushed by the roaster. According to Sweet Maria's the air temp and bean temp are fairly similar on the I-Roast.
