Curious if any research has been done on how many races/miles can be put on a pair of Dragonflies before the carbon fiber loses any effect???

The plate is not carbon fiber.
Ok. The ZoomX foam—does it have a life expectancy? Do the spikes lise their ‘Super Shoe’ effect after so long?
I don’t think you would run 6 marathons in a pair of Vaporfly’s and expect the same shoe feel/performance in race 6 as the first race. is there a similar performance decrease with the Vaporfly at some point?

I don't really know if many people reasonably track their mileage on spikes. Some people run them into the ground, others like new ones every season. Either way I think it's much more reasonable to go by feel when it comes to spikes than to try to define some set number when the spikes "should" be replaced. Besides, they're reduced enough to the point where injury concern is moot (they're relatively "risky" enough to begin with), and we don't run in them as consistently as our daily trainers.
That said, ZoomX is a lower density foam than traditional EVA or TPU, so what you get in terms of energy return, weight, and resistance to temperature changes, you lose in terms of durability.
