Hand speed is limiting...so we are told

[HungryBear]

We have been told that swing speed is limited by a persons hand speed. I question this conclusion as it appears contra to experimental evidence. I have a Medicus swing speed meter. The type that clemps to the shaft just below the grip. I have measured my swing speed both with this meter and with other measuring devices over the years. My swing speed, driver, is 100-105 and I can get a max of around 110. I get the same speeds with the Medicus meter on my driver. I have "experimented" but not found how to increase this speed. I am big and reasonably strong (6' 2" 225#). The club speed seems to be limited by how much effort is available, it gets very heavy at max speed. NOW the conundrum. I put the Medicus meter on a 1/2 shaft just below the grip and I can swing to a speed indication at the meter limit, 149 mph with a reasonable effort and speeds well over 125 MPH with ease.

The question is simple.

What's the reason?
