It’s a spider-based PM, so it really can’t. It has no way of truly measuring left/right balance, and thus Cycling Dynamics and even TS/PE cannot be calculated.
The PM industry has moved past the likes of SRM.
It is great to see a magnet-less option though. With solid temperature compensation and Bluetooth. Not sure how they are accomplishing pedal dynamics given what we know about spider based units - but still good to see them hopefully pull level on features with most competition.
Price wise, well ..

What kind of bottom bracket do the SRM Origins use - the 24mm spindle version specifically?
Keep a lookout for the chain catcher pin between the crank arm and the chainring. It's longer than in previous generations and can contact the crank (which will warp the chainring when tightened).

SRM says the PM9 + THM + 24mm Ti spindle is 444g which is around 20g lighter than my Quarq DZero Dub... at about 10x the price
