What I've noticed as far as rest is this:
Days 3-6 offer the most stonefruit.  You'll get a little bit of an acidic tang in these days as well, but not overpoweringly so.  These are my favorite days.
Days 5-8 offer a slightly less intense stonefruit, but you start to get a berry note added in.  It drifts between blueberry and strawberry for me.
Beyond 8 days (first, how did you manage to not drink it all before 8 days, lol) it starts to fade into graham cracker and lose it's dynamic parts.  Berry goes first, then the tang, then the stonefruit.
These are all notes relating to SO espresso, as that has been our main brewing focus with this bean.
I start dosing at 16.5 grams on day four (once had it at day 3, but it was a nightmare), adding about half a gram a day, maxing out at 19.5 grams.  We use Synesso double baskets.  Temps are always right around 201.5.  Shot yield is a targeted 24 grams over 26 seconds.

Just curious, why is there a difference between drum and air, and where do you make your adjustments between the two?
Looks like you did a shorter drying phase with air, and that's all. Is it that way for most beans?

On my PID iRoast, I did 300 @ 5 minutes, 410 @9 min, 435 @13min.
I'll have to adjust to try your profile, and taste the diffs.

Oh, I can. I can :D

Lovin' the PID. I've now figured out how to set up 4 separate 8 stage profiles on it.
