David,
I created an Imagine project that outputs an attractive graph showing you
the time/motion relationship between various start and end Velocity
Scaling parameters. It's wonderful to play with it, plug in various
numbers, and understand what those mysterious numbers mean.
I may not have time to upload it this week — needs a readme file, you
know — and I'm going on vacation next weekend, so be on the lookout in
about 3 weeks. I'll leave a message here to announce it.
Blaq!
