Did this just to see how much the cookshack
varies over time/temp.

Setting was at 200f with no food loaded
(just 2oz of wood so it would season a bit more)

Attempted (and mostly succeeded) in checking
every five minutes over a five hour period

Temp is temp, drift is the difference between
the current and last temp or the change in temperature
where up indicates the heating element is on.
Interesting curves at the bottom. I'd actually
like to hook up my lab gear but that's going to
take getting some thermocouples.

The setpoint appears to be a bit higher than the
knob indicates. i.e. 200 averaged closer to 225
and there was quite a bit of temperature swing.
Of course with food in the oven that swing would
be dampened.

Why? I had the oven cut out on me while doing
some ribs. Had to turn it off/on again. Problem
turned out to be a loose spade terminal on the
thermostat. Did this test to see if fixing that
fixed the problem.

Now there is a nice 4lb chicken smoking away over
some pecan wood. If hoards of flies are an
indication of success then it's going to be tasty.
