Brian, I don't know how relevant this is but, on my little machine, any script with a lot of little moves programmed hardly ever gets up to the programmed speed - i.e. EMC2 doesn't finish its acceleration before deceleration to the end of the segment starts. I suspec that this may work against what you are suggesting...
