Would you shed some light on what you think might happen please ?

What about the case of averaging? Let's say that you have motion of some object... such as the *collapse front*.. really a collection of objects as a descending destructive mass... and it accelerates, then meets resistance and acceleration is stopped or even slowed... then accelerates again... then is stopped or slowed and so forth many times. If you can't actually measure the movement on a fine enough scale the motion blends.
I use the analogy of a long drive where there are many accelerations and decelerations... some constant velocity and even no velocity... stop lights for example. The motion is *all over the place* but when you average the trip... it 40 mph and that's impossible because you had to at least accelerate to and then slow down.
I suspect we are using averages and that the floor masses slowed the acceleration and produced what APPEARS to be an average constant velocity... over the period of collapse.
