People are already starting to defend the legitimacy of their marathon PR that they got at CIM wearing Vaporflys.

I just ran marathons a few weeks apart - one in Kinvara 9s (Oct) and just did one in Vaporfly FKs (Nov). Similar weight, but the cushion of the VFs was noticeable and much appreciated throughout. Ran faster and more comfortably in the VFs. I'd wear them again for comfort alone.
But how much faster?
"I bought these shoes because they make you faster...but the results of my race had nothing to do with the shoes"
Vaporfly owners are too much.

Are the Minimalists rounding them up for the work/death camps already ?

What's that mean? (seriously asking here). Is CIM an easy course?
I ran a 10k in some newly purchased Vaporfly flyknits last saturday. I'm 54 and my good running days are long behind me. But I ran 90 seconds faster in the Vaporflys than a 10k I ran in light weight trainers 2 months earlier. I'm not sure I would have worn a shoe like this 15 years ago but the cushioning and responsiveness are unlike anything I've ever felt. My normal training shoe is the Hoka clifton - which is soft, but not as light or nearly as responsive as the Vaporfly.
I read that Gwen Jorgensen raced on the track in the Vaporfly. I would think a fast runner running the bends on the track would experience a lot of instability. The stack height of the shoe with the soft cushioning is a little disconcerting at first, and I'm slow.

Um, no. You can test this pretty easily.
they have tested it. flats should be worth 2 seconds per mile . if it is more , like 10-12 seconds per mile, you are wearing ill fitting trainers.
Prove it with a link to the study. I'm not believing this "study" you are telling us about. Personally, I've found it more difficult to hold sub-5 pace in my trainers (Nike Zoom Pegasus) versus my Nike Streak LT's. I feel if you're running 24+ min in the 5k, there is more ground for an argument. Otherwise, I don't believe an absolute statement like the one you just made.
vaporfly owners... try strapping mattresses to your feet you will experience the same blissful comfort although the matress would provide a wider based of support
the 4% faster is a placebo effect

Agreed
Looking at my race data from last 2 months marathons, I was 6.25% faster in the VFK over the Kinvara9 (based on a sample of later miles at same HR). But the weather and course were better for race two with the VFs so I can't separate out shoe contribution only.
I think the key performance benefit for me is low weight with high cushioning.
To the original poster, if you ran equal or faster than Eliud did at the last marathon the shoes wouldnt have made a difference.
