No, not at all. It might be off by 2:1 for all I know.

Yes.

I'm posting this on line since it may be useful to all
interested.

The tension values I gave ASSUMED Loos' tension was correct
for EHS. They were not actual readings on an accurate
dynamometer, so the pounds tension I gave could be anything
in the real world.

The only thing I was verifying is the gauge is very material
sensitive when two similar OD but vastly different stiffness
materials are measured.

Whatever they used to calibrate a stiffer material should
read higher than it really is and a softer material lower.
You can be sure it won't be the same if the material
changes.
