graphite geology for investors
the more graphite in the “lead” of a pencil the softer it is. one of the most important uses for graphite is in foundries. graphite is used to line the inside of moulds into which molten metal is poured. graphite is ideal for this purpose because it can withstand temperatures up to 3000°c provided oxygen is absent.
graphite - geology
geologic occurrence. graphite is a mineral that forms when carbon is subjected to heat and pressure in earth's crust and in the upper mantle. pressures in the range of 75000 pounds per square inch and temperatures in the range of 750 degrees celsius are needed to produce graphite.

my guess would be you didn't actually do anything. meaning the drift is just in hiding and will surely show its ugly head again soon. as the graphite contact wears away tiny bits of graphite shavings accumulate in the area and screw with the position-sensing.
