1) AeT determination can be done with the test on the first day of the plan you just bought. Not sure who you arrived at 132-134 but if you saw an upward drift of over 10% in an hour at 120 then two things could explain. Your assumption was wrong and you need to establish AeT. Or, you were pretty tired. AeT will change from day to day depending on recovery state.
