I'm reminded by something I read in the LTUP forum on another site about way back when the consensus was that the world was flat. The consensus didn't make it right, the consensus was simply the number of people who were wrong.

If the advise from an "expert" stops you from crashing your plane then it was good advise whether it was technically right or wrong. If the advise from an expert stops you from having fun with your plane then it's bad advise.

Don't forget, the bloke who won this year's (and last years) MotoGP world championship probably couldn't name four ingredients used in making the tyres he was running on so asking Marc Marquez about tyre compounds or construction might not as be insightful as asking the bloke at Bridgestone that's never thrown a leg over an RC213V.
