Yep, FC @ 7, then dump at 9-10, agtron 58, is pretty much SCAA standard for a sample roast. What I'm finding is unusually low drop temps, high airflow and low gas settings are needed to achieve the 'standard'. Definetly want a gas flow gauge as the flow knobs are very imprecise and the same position on both barrels can result in large differences in heat. I need to do some more playing and cupping before deciding if any other mods would be worthwhile.
