Scroll effects speed fine tuning question

I’ve been playing with the vertical scroll animation effect applied to several objects on a page. I’ve noticed that the speed value works in increments of 0.5 or something like that. For example, I have two objects set to move vertically at a speed of 1.1 and 1.15, respectively. In the browser they move at the exact same speed, no difference whatsoever. I assume there is a rounding somewhere in the JavaScript code. Is that by design?

There is not. It’s probably more about the exact setup you have, with amplitude of the motion not being enough to show meaningful differences between 1.1 and 1.15. Hard to say without fiddling with your project.

I made a test file using some 5x speed values:

On my computer, the actual movement of the boxes when scrolling does not appear to precisely follow the speed values set in the Vertical Motion panel. To me it looks like there is a threshold or rounding somewhere.

I stand corrected, thanks for the excellent sample. We’ll look into this.
