To an extent agree but to a much larger extent you'd surprised how wrong you
are. There are some very very sophisticated roast monitoring and control
systems in use out there. Light years beyond the whimpy by comparison $5k
control system on my little roaster.

Yup, even with the most sophisticated equipment you still adjust according
to taste, bean condition etc. Last batch of Delirium tweaked one of the 5
profiles 2 degrees lower EOR, another 30sec quicker SOF to EOR keeping same
finish degree. The more sophiticated the system the easier and quicker it is
to dial in a desired end result change. That's using SCIENCE to implement
(not replace) the ART.
And yes this applies to home roasting. I used the same principles profile
roasting with my Frankenformer dual variable boosted voltage controlled
Caffe' Rosto from many years, likewise Mike (just plain) PID'd Ubber Popper,
Jim Schulman PID'd FR, I forget who (sorry) PID'd controlled HotTop, my and
Mike Chester's Jeffrey Pawlin designed Computer Controlled HotTop and the
list goes on and on of serious profile controlled home roasting.

Ultimately the quest for Koffee Nirvana is a solitary path. To know I must
first not know. And in knowing know I know not. Each Personal enlightenment
found exploring the many divergent foot steps of Those who have gone before.
