I agree!

No, rescaling means exactly that, and as you yourself stated "the proportions stay the same". What you did was just plain silly and an attempt to confuse the issue, another strawman argument of yours.

Maybe it's because this thread is such a mess, but the only "line template" of the arc you are using is in your own photo account. The attempt to shorten the template is a response by the template worshipers to make it relevant when it hardly is.

Bingo, half way there. Now if you can only see a wing as I do (see below) and acknowledge that arc is representative of a section cut, you might understand why the 3D shape and its side curves or terminations are so important. This is the drag you should be concerned with. Oh, and wings come in different sizes (LxWxH) yet may use the same NCAC profile (ratio), getting it yet?

Maybe you should look at it in more than section, try plan view or perspective once in a while. Wings don't go on forever, they have edges - and messy ones too

I like the template arc for what it is, a starting point, and one I still use. It is however nothing more than a reference, it is not even a design.

By people you mean "me" when I draw things? Then yes, but everything I've drawn is also supported.
The CFD illustrations are a pretty good guide, I really don't think people are manipulating them by what they choose to think. They are only choosing which points to tag and follow.
Okay enough wasted time, took my lunch break, now back to work y'all.
