50 foot of hose will have a fair loss.

This is just silly. Two THOUSAND feet of hose would have zero loss, unless
it had leaks! As PT aptly pointed out, the gas laws prohibit any pressure
in a closed system from being any different anywhere.

Correct!!!

If you cannot get more than 98lb at the end of a 50' hose headed by 120psi,
then you are A) not waiting until the pressure finally reaches its
asymptotic limit [which it MUST, absent leaks], or B) have leaks -- major
leaks.

I think that there is a pressure loss at the Schrader valve or some
such, like a spring that needs to be pushed by air.
