Thanks for this response and so I want to flash back to this one:

The curve is similar to this one you posted, but just a bit more curvy at the end. Should this process of working out the curve be custom for any given rotary system? It seems like I could use any of these equations and they would be in the ball park, but I'd probably want to go through these steps on each robot, and each closed loop rotary system because of other properties like model of victor and the work load that it is controlling. Well that is really the question, does the work load impact the kind of curve you will have? Are there other factors which may contribute to the curve being different from one robot/rotary system to the next, and if so, is it significant enough to be worth the effort?
