Starting from the last question, is the easiest to reply: other people PID parameters will never suit your own machine, if not identical build and beans.
Actually, there another simple reply to everything: don't use PID, is simply not appropriate for this kind of process.
If really interested to go deeper I can elaborate more.
As measurement setups I am using either a Mastech MS6514, either a custom build board that run a fork of TC4 software.
About the strategy what temperature using as profile, use BT only if you are very sure you take it correct and reliable, measuring as much bean surface and less air as possible. If a right BT measurement can't be done, then an ET based strategy give much better results. How to roast with ET as reference, read here:Timing first crack heat reduction
Don't be obsessed about horror stories about FC flacks and crashes, they are specific to drum machines, not so perceivable in the hot air majoritar convection machines, as FB or hotgun.
PS: I guess the image you posted is not yours, wondering if it is even real, or some sort of simulating, as I am doing using software...
Is hard to believe that starting from such oscillating ET can result so smooth BT curve, and even more, so unrealistic smooth RoR...
