I have noticed that CCPM devotes somewhere around 50% of the available servo throw to the collective movement and the remaining throw to the control surface.

My question is this... when trying to accomplish a throttle linkage geometry that will stay ahead of the collective movement when the coordinated servos that add collective pitch need only to move (rotate) half the amount of the throttle, the throttle servo does not have a chance of keeping up!!.

What are any of you doing to combat this?

I agree with Nate's description of this. But to this I would like to add that your throttle servo is not going through full travel either. For example, the mid point of my V curve is 60. So my throttle travel is limited to 40% of its throw. Now if yoiu go from full positive to full negative collective your throttle will still travel at most 80% of full travel. This is more than the 50% that the collective will go but think about it for a second. Suppose the throttle can't keep up. It will actually be above where it should be as when you go from full stick to center stick the throttle is closing.

Just my oppinion, but I don't think you have anything to worry about.
