A pendulum cannot go left, right, and then left again without first going to the midpoint and then going further right. That is the nature of a pendulum. You’re describing something that isn’t functioning as a pendulum.
If you were looking at a pendulum’s path as the bottom half of a clock face, you’re describing a pendulum that drops from 3, stops at 5, bounces up to 4, goes back to 5, and then back to 3. That’s not a pendulum movement.
The whole pendulum effect is that the harder you push us into the win column, the harder the force is going to be pushing you back into losses. Football programs build pretty much the opposite way. The more momentum you get going toward nine wins, the easier it is to keep winning nine.
