I wrote some code to process my holdover logs from the Thunderbolt with the newer "flat line" rev E2 temperature sensor.
The data is a lot more consistent than I thought it was. I am seeing around 9.5 uS +- 0.5 uS of drift in the PPS output per degree C across 4 different 24 hour runs. My analysis is very simple... scan the log and calculate (MAX_PPS-MIN_PPS)/(MAX_TEMP-MIN_TEMP)
It will be interesting to see how the unit performs with the old revision C2 ("better"?) temperature sensor.
