Basically without a way to stop travel on the softer spring you end up somewhere in the middle on rate and compression. I have stated I would love to have a video of the MSS set up to see how these springs are actually reacting under load.
A multi spring arrangement is very similar to a progressive spring, but has one main difference. In a progressive spring the rate has more of a bell curve. The rate tends to amplify pretty quickly. As a user you are not able to tune when the next spring rate comes into play. In a stacked arrangement the user can tune when the rate transitions via the use of different main springs, or more forcibly through a crossover ring to stop spring travel. In the case of the MSS kit, the progressive tender does in fact coilbind and place you into the main spring. It doesn't take much additional load, the tender is nearly at coilbind at static. Using a progressive tender means the rear has a third rate which is helpful for providing an even softer rate for pothole additional absorbtion. The stacked arrangement provides for a linear rate as you move through the spring travel. It has less of a smooth/sharp rate, and more of a straightened path as you coilbind. Tuned correctly this can give a more pleasant ride quality as it ramps up.
The main benefit is really on bumpier circuits, where the car can ride on a softer rate and maintain composure before moving into the main rate to control body motion. Think Sebring International, super bumpy circuit where you need both compliance and control. Unfortunately the MSS Kit doesn't employ this same stacked arrangement on the axle doing the steering, ie the front. This would have amplified grip.

If you already have Dynamic Plus, it would be much easier to switch to a complete coilover kit. The MSS Kit option provides for great spring balance, but does not give you a shortened shock to cope with being lower. Nothing worse than getting into a corner and hitting the stops.
