I twice recently roasted some Donkey blend decaf and stopped it just
short of 2nd. During both roasts there was one or two outliers for 2nd
so I stopped before 2nd really started. The roast was excellent in both
cases. And my time between 1st and 2nd was reasonable.
Which raises my question(s): Is it just me, or am I not having the same
'fast roast' issues that other air popper roasters have? I am using a
basically stock P1. I get a fast ramp into 1st (like 2 - 2.5 mins.) and
then  once 1st has finished  I can go  as long as  3 to 4 minutes before
2nd starting.  In some cases my roasts  have lasted 10 - 12 minutes
total. I am 'controlling' the heat during the roast by simply removing
the butter tray and/or the whole top to slow the heating. FWIW, I am
roasting in my garage adn the ambient temps have been in the high 40s
and low 50s.
So again, is it just me, or is this more complicated than I'm making it?
It seems awfully easy to control my roasts with little more than a
little manual intervention.

No - with the right equipment it's just as simple as that.  You may be
getting a little heat regulation from a cycling thermostat in between
1st and 2nd which is working in your favor.  If the unit starts having
a hard time getting to 2nd at some time in the future, I would
consider some mods to the thermostat.  Sometimes these things change
with time.

I neglected to mention I am using an *almost* stock P1. One of the first
things I did was remove the t-stat as it just wasn't letting the unit
stay warm enough to even get out of 1st. So it *should* be roasting even
faster. But at least for me I have found an easy way to regulate the
heat by simply opening up the top. It works in winter anyway. I assume
I'll have issues as the weather warms so my next mod will be to split
the line and cycle the heater on and off to come closer to an ideal profile.
Before I get into the really sick mods...

Ha! Don't get me started. I haven't modded seriously yet because I can't 
just do anything a little bit. I am planning and thinking all day about 
what I will do. Meanwhile, I'm enjoying some great coffee. I mean truly 
great.
