Sram Rival PM question

Does anyone know if I’d be able to temporarily set this up with a DUB PM on the drive side to test accuracy? I’ve at a Rival crank on my gravel bike and a DUB PM on my mountain bike. I’m a bit nervous about the power discrepancies reported but I was thinking I could hook up my present PM (which I trust) to this and then use DCRainmaker’s file comparison tool.

You can use zwiftpower and test one PM against trainer and than second and if you see trainer as a constant than you can get the diff

No you cant as the spider in the Rival crankset isn’t a separate part from the crankarm

Did you (or anyone you are aware of) retest the rival PM after the software updates? Anything new on the accuracy issues?
