I still have one more roast to finish and a bunch of measurements to take and numbers to crunch, but so far it looks like what I expected to see out of today's experiment is supported by the evidence (that one control strategy does, in fact, produce less variable results across different coffees, meaning I have a recommended practice for improving sample roasting consistency on that machine).
Doing some #SaturdaySciencing today. Given an automated coffee roasting system with two different parameters control can be based on, a plan on each such that events happen at the same time, same total roasting time, does one control strategy have less variation in degree of roast across coffees with different physical characteristics (moisture, bulk density, &c)? Let's find out.
