Maybe I gave up too early :-).

This is the problem as I experienced it:  the stiffness of the
transferhose varied with gas pressure inside it.  The forces the
hose transferred to the tank varied with the pressure.

I imagine that if you could keep these variables under control
(or null them out) you'd be close to home and you can always check
at the end after the fill hose has come off the tank.

Sounds plausible to me.
Let us know if it works.
