If everything is the same, it should be consistent. There will always be a temperature drift, but if the drift is always the same, it should be fine. If the ambient temperature is vastly different, it could be a problem.
I work out in an uninsulated shed, where the temperature can be below freezing. This has a large impact on the accuracy of the trainer (Tacx Vortex) because the difference in starting temperature and “optimal working temperature” is so large. In this condition, 10 minutes is far from enough to warm up the trainer. The last few workouts, I have tested this, by calibrating several times and comparing the numbers. When it is around freezing, it takes around 45 minutes to warm up!
Last winter I did a 2 x 8 test, that gave me a suggested ftp of 316, when other rides indicated it was between 250 and 260! That’s how much temperature drift can affect your numbers.
