This is a moot point - since there is no such thing as spherical measurement in this context.
All distance measurements in this context are point-A-to-point-B flat measurements - land, sea, or air - no curvature is measured - only distance.
If you map flat data onto a sphere - and then, later, you translate it back to flat to make a flat map - it does not mean that the landscape is a sphere.
For the whole process, it is only assumed to be a sphere - or, that there is curvature present.
The math may sound really good - but it is only math - and does not necessarily reflect reality.
It is pretty silly that you would try to back him into a corner with such as this...
I believe it is entirely possible for him to use a map that he does not think is completely accurate albeit he still finds it to be useful.
Not to mention - if it happens to be the only thing available...
No one ever has to "admit" that a map is 'accurate' to use it. Trusting it is a whole other issue...
In this context, I believe spherical geometry is faulty - because, the curvature is assumed instead of measured.

"silly" ... said the man who believes the earth is flat.
Flatties should take their own measurements without using established knowlege that they reject .
