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.)
