Okay, about that decaf Sidama that a few mags are roasting now:
I found that this coffee DEFINITELY races, but it's still quite manageable in the drum. It doesn't seem to tip or char too easily, so you should be able to charge quite hot but then make big moves early on to keep it from racing. This profile is the one I've settled on for an unabashedly crowd pleasing coffee (trading complexity for sweetness, which for my use cases - affogatos, lattes, and feel-good coffee, is perfect) - if i really wanted to pull more nuance out of this coffee I would cut my dev time by like 8-10%, easily. Fuck that though, the point of decaf is to serve it with ice cream and in martinis and in fucking decadent whole milk lattes. Save the light&bright shit for 6:00am pourovers.
So - to do this, I charge hot as fuck, but then I pull off gas very quickly in the profile. charge at .25KPA, roaster idling comfortably at 395, at turn, gas to 2.5Kpa (i wish my turn was a little lower tbh) At 4:10 (dry end) I went from 2.5 to 2.0 kPas of gas, and then again at 5:00 down to 1.75, at 5:50, 1.5kPa, 6:35, 1.25 kPa, 7:25, 1.00 kPa, coast til 1cs, at 9:00 (1min post 1cs), gas@.5kPa, at 9:30, gas at .25kPa. So like, the general trend line is, big moves early on to keep the coffee from racing. Still, you can see - the coffee WANTED to race through the maillard stage, so you have to balance dropping heat from bottoming out and stalling the roast.

sorry i'm a hack and i still don't record my gas changes on my profile - still, big moves early is the theme of this coffee.
*edit* re-reading jackattack's comments, the dude is absolutely right about this coffee. he's done like 20 roasts or whatever and he already has a strong command on this shit, FKNA. you nailed it though buddy, it sounds like we landed on very similar profiles
