Which model is it?
"MagicZero is a feature of Firmware 10 and is available via the SRAM AXS App for all AXS and DZero power meters."

"Typically, the MagicZero measurements occur when the bike is stationary, coasting, or slowly backpedaling."
So it is kinda similar to Powertap, but a little bit smarter by the sounds of it.

That’s what’s confusing me too; every metric is consistent throughout the TT expect power, which jumps up to expected levels at the 5mi (lap) mark.
I mean it was cold yesterday morning and warmed up quite quickly but would that temp difference (about 3 degrees) have resulted in this? Avg power recorded for lap 1 was 203w (essentially low tempo level) and lap 2 was 287w (c. threshold).
Will give it a steady run on the turbo this morning and if there’s any more inconsistencies then I know the meter is playing up.
