Looking at the ‘photo’ associated with your activity, I don’t see the little ‘lightning bolt’ next to your name, which would indicate that you didn’t actually connect your power meter to Zwift as your power source. Hence the ZPower assignment.
For what it’s worth, it looks like your power meter was your source of power for your December 31, 2020, race, but you were on ZPower for your January 10, 2021 activity and appear to have been since (though you haven’t had many activities in that time period).
he’s mostly correct because they both use a misuro b+ sensor to estimate power rather than taking a power measurement from the unit itself, a method which zwift sometimes recognises as ZP, sometimes it doesn’t. i don’t know the logic behind it, from a functional standpoint i’d consider it a form of ZP though.
probably not but if you don’t race then it doesn’t matter. and even if you do, there are some events that don’t exclude ZP riders from the results. my dad (not on zwift) uses a muin though and it overestimates power like crazy, so i wouldn’t trust the numbers from it
events on zwiftpower with this tag will most likely DQ you from the results
