I've never tested a Digifant one, but on L-Jet systems that was normal.
It'd ramp up, then drop, ramp up, then drop.  I really don't understand
how the ECU gets useful data from this, but it apparently does.  What
you're looking for are spots where it doesn't make contact at all, or
gives a ridiculously high value.  They're prone to developing bad spots in
areas where the engine runs for long periods of time.  (Hondas have a
similar issue with throttle position sensors.  If you run on flat ground
with the cruise control on all the time, eventually you wear out that one
spot on the TPS.)
