Reply to "100 mph"

"One of the early forms of determining pitch speed was by measuring the speed against a motorcycle flying past."

They had trains that could do it in the 1890s. I know a lot about measuring bb speed and never heard about motorcycles. Early methods measured how far one could throw a bb in one second which could be measured very accurately.
But that would measure average, not peak speed.

Easiest primative way to measure speed is to simply see how far a ball can be thrown. 300 feet in the air takes about 90 mph. Ball thrown at 30-45 degrees.
