Do keep in mind that switching to the trainer power data may yield different results. Despite claims from makers, we frequently see wide differences in data values between meters and trainers. So, it may be fine and close in your case, but be aware that if it feels off, it may well be due to deltas between devices.
Testing without PowerMatch is worthwhile, because it simplifies the process and can reduce adjustment lag to a notable degree. So it is surely worth a test, just keep power feel in mind.
