That’s unpleasant and makes even harder to isolate what causes this.

Due to current workload, I haven’t had chance to play with it more. I think your expression works well. The different results I got from my experiment may due to I wasn’t using factor of 60 for scrolling duration, I can’t remember for sure. So as long as scrolling duration is factor of 60, then the expression should work as expected in 1.8.1.
