The movement
Arcs fail at the trough, not in the photograph of the finish.
A pendulum does not go false in the middle first. The beat widens, the bob arrives late, and the clock still looks busy. Iron paths fail the same way on Barstow.
We hang a paper bob from the shaft and chalk where it refuses to sit under the ball. That pale slash is a late trough. Chippewa mornings accelerate it because cold air stiffens the suspension and the first swing of the day arrives fat.
If the through-side is late and the backswing still true, the path is two clocks. We will not shorten the living half as a kindness to the dead half. Nels marks the through-side as shorten and the backswing as leave.
Players who want one verdict for the whole six are asking the gallows to average a square beat with a poster. The bench declines.
