Can the ATU "compensate" for feedline loss?

My initial question related to a dipole 3 feet too long, no change in
feedline was/is contemplated...consider that a constant.


The length of feedline(s) may be constant, but the losses in the
feedline(s) depend on VSWR, and nothing you can do with an ATU changes
the loss in feedline(s) beyond the ATU.

I note that you have figured that the dipole is 3' too long, that is
about 3% too long, but the antenna resonance appears about 6% low at
14MHz. Are those two pieces of information consistent?
