Stages (L) vs Hammer H3 - Which can I trust?

[AJS914]

I made this topic when I was trying to figure out my Stages.

Stages vs the world comparison testing - Stages Factory reset made a big difference

Sadly, all this leads me to believe that my 20 minute power is no where close to 300 watts. I’m still way stronger than I was last year. Last night I did a race simulation club ride and made a new best power on every point on the PMC in WKO5. At least I know now that my Powertap and my Stages are very close and my Tacx Vortex is way off.
