Yes any time you change the power setting you need to recalibrate to get an accurate reading.

I think you need to recalibrate when you up the power going into the meter.

just a third yes. you need to recalibrate any time you change the wattage going into the SWR meter.

this is why i always turn my mic gain down when doing SWR tests.
noises cause a jumpy meter!
