Power is the rate of doing work, where work = force x distance. Both the former and the latter can be, and in the case of Stryd are, measured based on acceleration.
Or are you one of those punters who never made it to uni and mistakenly believe that a bicycle power metre somehow measures things more directly?

yeah, any ‘punter’ can google this but Brick Top won’t have you slagging a cycling power meters in this way
so the torque equation for the Stryd pod is what exactly?
oh that’s right, it doesn’t measure force at all, it is a reflection of ‘metabolic’ power, which if you even had the slightest understanding of the device or the early adopters would already understand that and the distinction between ‘mechanical’ power and ‘metabolic’ power, but were all just punters here after all
were still waiting on your dissertation to illuminate, gee, no ones knows wtf you are actually trying to espouse here other than you think youre more educated than everyone else with pretty much F all to prove that hypothesis
You feel isolated. No friends, no family, and nobody cares about you. You're an outcast, spending your days alone at home, posting on message boards, hoping for even a little attention. You will spend your life questioning why everyone seems to dislike you or why strangers instinctively avoid you. Sensing the hate, contempt, and misery you try so hard to conceal. To prevent a lifetime of suffering, here's some advice that no one close to you will share. Start by getting your life in order. Clean your room, tell the truth, and genuinely commit to improving. Be kind, honest, and authentic. Stop deceiving, manipulating, scheming, falsifying, minimizing, misleading, betraying, and rationalizing. Your life can and will improve. Others will want to be around you, and you won't have to sit alone filled with agony. Embrace life’s joys. It's never too late.

Someone get Avril Lavigne out of retirement, lay down a few power chords and a straight 8 - 'cause ladies and gentleman, we've got a hit!

Stryd measures force based on the acceleration it creates
Most cycling power metres measure force based on the material deformation they create.
Conceptually, what's the difference?
Or to turn things around the other way.
What do you think it is that Stryd measures, and why is it quite good at predicting running economy (R squared greater than 0 9)?
Maybe it's just a fancy party trick, like the one Schroedinger's cat always used to pull out?
Another ex cyclist here. Maybe we all found the thread by googling running sweet spot? Seriously, that's how I found it.
Btw, whatever your argument that I can't keep up with, and whatever it measures, as someone else pointed out, a cycling power meter you can put in any situation and it works. A Stryd, as fun as I have had playing around with one, just doesn't. That makes it maybe useful for someone who runs in the same conditions, 90+% of the time. But, for most of us, utterly defeats the point of power. In that power can/should give you a cost of the effort, indoors, outdoors, in the cold, hot etc. 250w is 250w (I've just given away how bad a cyclist I am with my FTP) and you can adjust accordingly.
With a Stryd you are relying on a fancy algorithm within a what is basically an expensive Garmin foot pod. Not that it doesn't have value, but until you can do something like run into a massive headwind or up a steep hill and rely on it, it's hard to really even call it power.
Just my two pennies.
Btw, great thread for the most part. Starting to see the gains of this now 4 months in. Thanks to all the testimonials, a great help and confidence that even if early on you don't see many gains, to keep going. Although I have only been running two years so I guess I still have noob gains.
Very much in the spirit of how British time trialists train, which isn't surprising given sirpoc background and how he was a local legend in that as well. Great book as well. Btw, if he still reads this, would be great if you could perhaps release even a small guide for aero testing? Even just knlkne. Especially as I am thinking about giving some time trialing a go again. A friend of a friend told me about your legendary CDA on the cycling scene. It's a shame you can't shave 1-2+ minutes off your time doing what you did for cycling in running lol the ultimate cheat.
