With the commit of r22863 ("e200v2/Fuze: Improve scrollwheel a little bit by assuming the previous wheel value if no new value was found (which happens if a single wheel value was skipped). Only assume it once to not get wrong readings."), I am seeing a decrease in scrollwheel accuracy on the Sansa Fuze. Quite often now, at the very end of scrolling to an item in a list, the pointer hops 1 step before (or, less frequently, after) the desired line.

Related to this behavior: Continuous fine scrolling up and down between two adjacent items in a list causes the pointer to wander erratically much farther up and down the list than expected.

I have not performed tests on a Sansa e200v2, but I wouldn't be surprised to find similar results there, given that r22863 addressed both devices.
This task depends upon

I can confirm the same behavior on the e200v2 beginning with r22863
