Hi Mike! I've noticed the need to hit the gas as the RoR is coming up after turnaround to avoid that quick drop after the RoR peak. I subscribe right now to the Scott Rao commandments, so these tips are consistent with that approach. I've also found that depending on the bean I sometimes need to also boost the gas a little after 1C after having come down on it throughout the roast.
Turnaround seems kind of high for your low charge temperature. I'm wondering if that is because you have a very small charge? Might be helpful to include your charge weight in your profiles (under roast properties).
I know you've got a lot going on with learning a new roaster and Artisan (presumed) but when you get a chance, I've found adding event buttons to track gas settings and fan or damper settings is really helpful.
Do you have the damper? IS this your first roaster, or what are you used to?
