Before doing any ABA testing one should warm up the car for at least 10 miles, and probably much longer if the temperature is anything less than 24C / 75F (as your graph seems to bend at that point); otherwise the first A measurement would have relatively low MPG.

Absolutely! In fact, probably even longer as the transmission warms up more slowly than the engine.
