Apparently I had it backwards then, template was shorten not lengthened, not sure if all that was ever posted or just what you dealt with in the backroom.

A poster named Tesla back in 2013 was attempting to use or compare to NACA 0039 profile. This had a longer Cod's head.

I was the one that did an overlay, not that I recall doing so.

Interesting thread, possibly related.
