So somehow, Emacs receives a long series of mouse wheel-scrolling
events, perhaps due to multiple down-mouse events.  And since we have
mouse-wheel-progressive-speed, a series of such events produces
scrolling far away.

The question is where did those events come from?  Is it possible that
something is wrong with your mouse wheel or the driver?

I don't think so.

How would that help?  You'll most probably see very close times there.
