Yes, slow the ramp at start of 1st by reducing heat, in my case reducing
heater voltage. Not so much that temp rise stalls, but rather slows to
desired rate. FWIW my roasting method my batch size usually maintaining =
full
fan 20% boosted voltage of ~144v. Also note that with my roasting =
methods
the beans are not racing but rather slowly moving in horizontal circular
motion with donut shaped Rosto stainless steel roast chamber, kind of a
cross between typical fluid bed and typical drum roasting..

Mike said "Anyway, I slowed to ramp @ start of 1st 400f to 10f/min for 2
min.
Do you cut heat to slow to ramp? 1st crack naturally slows my roast =
down.
The 1st min.
of fc 4-8f/min 2nd min 8-10f/min

 Don't forget the enjoyment of roasting by getting caught up in
watching too many instruments.

OTH part of the enjoyment of roasting for some just might be watching too
many instruments!
I'll tell ya, a couple weeks ago a cold was kicking my butt. At best sense
of taste and smell maybe at 20%. AND needed to roast coffee. The element of
judging roast finish by smell was for all intents and purposes non-existent.
I was very glad I "could" roast with good accuracy almost totally by
instruments.
Now roasting this week with full senses active much more plearsurable to be
sure. Man I just LOVE the smell of roasts going through 1st to end of roast!
And really find the bean smell changes from start of roast green, to
tanning, to browning both enjoyable and informative too. And if not for
sense of smell the Harrar Lot 30 roast would have been blown, ramp from
start of 1st to end of roast target temp went a bit too fast. When hitting
targeted 450f tickling 2nd finish point there was the barest perceptible
hints of blueberry just starting, since the final ramp had gotten a bit away
arrived ~30 second early (don't scan List email while roasting if you be a
human PID:-), so simply held the desired finish temp for ~30 seconds and the
expected blueberry fragrance suddently exploded. Happy Roaster:-) FWIW this
mornings early 3 day rest "blueberry" cappuccino quite good.
I call my roast style Artful Scientific Zen roasting:-)
