As I stated earlier, the horizontal axis is NOT necessarily an accurate, or even proportional time axis. If analyzed with a high speed camera I suspect a more accurate horizontal time line would look like this.

In other words, the phase of Constant Acceleration is over in milliseconds.
This diagram also does not link that important phase physically to actual rod position. When we analyze an actual casting stroke, even given the difficulty in defining the exact transition moment from loading phase to acceleration phase…it becomes obvious that the acceleration phase occupies a very small slice of the necessarily limited casting arc.
To analyze what is actually happening review our model.
