I think the issue would this would be the "controlled setting" part. The amount of driver induced variables are so much lower in a car test then for a DH bike. Car test results don't depend on what you ate for breakfast, how tired you are etc etc etc. Even if you're comparing by lap times, there's not nearly as many line choices.So I have owned 15-16 DH bikes since 1998. Many of which a good number of people would consider some of the best bikes of their time.
In all my years riding MTB you know what I have never seen? I have yet to see a timed run down a controlled trail with the exact same parts on different frames. I would have to say numbers don't lie if a rider can turn an equal time on a SP vs a 4-Bar, VPP etc. then you can just call all the claims of any real benefit marketing correct? I would do this on my personal site if I had $15,000 to blow......but right now I do not.
I know I can walk into a Nissan dealer and order a GTR that will beat all cars on the planet but a few that are in upwards of 1 million dollars. The reason I know this is because the numbers are out there for people to see. It might be a hard pill to swallow for some but actually having their product tested on timed trails would show the pluses and minuses to designs and what is marketing versus what isn't.
I think a couple months of Deca or EPO use would benefit most Elite Gravity riders more than any frame design might.
