Ah, the Leaning Tower of Pisa
Directed to the OP's question....
I believe the reference to eiffel taper would be that it is not a true conical taper but more of a curved conical taper. If there is such a thing.

Skinny top, fat bottom ?
Not sure if it is a hyperbolic or parabolic curve, depends on the path of the tool used to generate it, across a cone.
Raise the the tailstock of whatever is being used to rotate the shaft for machining.
If a ball end router bit were to be run overhead along a parallel path with the centerline of rotation, a cone will be generated. Run it diagonally across the top, and a curve will be generated.
For a cue, it is not desirable for the tip ferule end to bell back out. The intersection of the diagonal overhead path with the shaft center of rotation would be at or past the end of the ferule. The location of the starting point off to one side at the joint will take some experimenting.

Yes, it's called a parabolic taper.
