someone was bullshitting you.  getting the resistance to rise at the same
rate is only as difficullt as getting the resistive carbon film track to
have the same width and thickness along its entire length.  Wether they use
vapor deposition or a liquid process (screen printing?) that's not a
difficult task.

doing the semi log ones must be more involved getting more resistance
(therefor less material) at one end than at the other. - maybe the spray it
on amd vary the feed rate (or pressure) to the spray head (or the rate of
motion of the head).
