[Interest] Auto SmoothedAnimation?

[Jason H]

I have a progress bar (Rectangle) that I update the width on a fairly regular interval. I've tried using SmoothedAnimation, but it smoothly fills, pauses, then fills some more. I've read the docs that talk about velocity, but as far as I am concerned, this should be automatic. Velocity should be a exponential moving average of the value, divided by the EMA of the time interval, so that it will adjust velocity accordingly.

Or am I using SmoothedAnimation wrong?
