As in, the template is the greatest misapprehension here - but what is the next greatest?
Without a doubt, the significance and action of aero pressures acting on panels.
When Vman455 showed some of the measured pressures on his Prius (data that immediately contradicted much of what Aerohead spouts), I was amused to see no-one actually 'got' the contradiction (or no-one who commented, anyway). I was amused but not surprised - because the same thing happens here when I show my Insight's measured body panel pressures.
Aerohead's ideas in this area are again quite wrong, and again they seem to have been adopted widely here. And - yet again - it's because people don't make measurements - if they did, they'd soon see reality for themselves.
A good example is the person from this group who commented on my 'don't use a template' video. He looked at the Jaguar's CFD pressures (shown in the video) and had them completely reversed! That's sure some misunderstanding.
And I might add, the reason for that complete misunderstanding can be related back to the silly template - you could see that's what he was trying to build his ideas on. But crap in = crap out.
