I am pretty sure that the air temperature that matters, i.e. those hitting the beans on the roast chamber bottom, i.e. exhausted through slot openings, is much hotter than your measurement.
As a rule of thumb, if you have FC at minute 9, should have about 250 C. Add/subtract 10 C degrees for every minute sooner or later. Just a rough guess, but closer to real than 170.

A brand new popper has a first stage thermostat set at 180 C, to protect the popcorn from burning, do you think it ever trip if only 170 C in the can at full power ?
