>Thank you very much for spending time on this, I appreciate it!
You help everyone out too, it's nice to be able to do something for you for a change.

Thanks for the explanations, now I have a better understanding of what it needs to do.

Although the idea of just splitting the profile in half and doing the exact same thing in reverse for the second half was interesting ... that's what's causing it to only move to multiples of V_Max. I need to change that.

And I need to make it go both directions, it only goes forward right now.

I hope to have something by the time you wake up in the morning.
