Seems to suggest that there's an almost immediate drop off in foam integrity.
Personally, I will only do an A race in a brand new pair of super shoes. I do less important races up to about 250 miles, but usually by that point I have another fresh pair coming down the pipe from my last A race, and then the shoe becomes just for workouts.
I'm 6'3" 180 pounds and I have around 360 miles on my next% 2 and they still feel really good. I still use them for speed work on the track, tempos and long runs.
The only difference from a brand new pair is the outsole rupper peeling off a bit under the toes that was caused by 200s and 400s on the track. I still plan on using them for my last couple long runs and tempos before my marathon in a few weeks.

That's just showing the variability in the runner from day to day. Look at the Metaspeed Sky, with an improvement on Day 2.

I’m a 130 pound OTQ hopeful. I race in them for 100 miles, do workouts for another 200 miles, then use them as regular trainers for another 100 (400 miles total). I land mid foot.
I’m 165 and nowhere near OTQ (2:49 PR) and I have the exact same rotation for my Next%’s. At 400 miles, they are still great for easy runs.
The truth of the matter is the following: They are actually free if you are a big enough of an a$$ with no moral compass.
To date, I've bought two pairs of Alphaflys and another pair of Vaporflys Next 2's, worn each for the maximum of the 2 MONTH return window during peak marathon training, basically maxing out the life of the shoe in that window. Then return for full refund. Perfectly allowed within the policy. If they ever caught on and banned more returns I'd start shopping under a different identity. I have kept several pairs that I did purchase to keep long term.
Oh poor Nike!! How will they ever survive with their measly 47 billion annual revenue??
Get over yourself and get off your moral high horse. This isn't even a noticeable drop in the bucket relative to any other form of shrink.

I think you might be reading that wrong. That demonstrates there’s no meaningful difference in his running economy from fresh to 200 km, and a very minor difference by 400 km. It corroborates my mechanical testing observations spot-on. The author of that posted earlier in the thread (Lab Rat Rundown).
I will add that I think the AlphaFly is more durable than the VaporFly. The rubber pieces on the heel help the physical integrity, and the air units under the forefoot have a nearly infinite lifespan (assuming they don’t pop or leak).
