26. No I didn't miss that point

The graph indicate the the second floor (and subsequent floors) each fell as if the floor was only under the influence of gravity until it hit the subsequent discrete floor. That is not physically possible

Think of two billiard balls in a vertical tube. One is ten feet high and the other is five feet high. When dropping the first onto the second, the first does not momentarily stop after hitting the second ball. And the second ball does not fall exclusively under the influence of gravity. Quite a bit of energy will be transferred to the second ball to give it a far greater velocity than if it was just dropped from an initial velocity of zero and allowed to free fall.

The model I just presented is exactly what the graphs show except it models each floor falling under only the force of gravity. Each discrete floor falls as if it was disconnected from the tower and fell as if there was no impact from above. As I said the graphs look nice, but they do not represent the pancake theory.
