Merlin,but is it the same in real life?
That is always the question, but getting some experimental data would not be easy. Maybe Dirk could the the marked line he used for his square snaps measurements to track some markers on the fly leg, loop front, and rod leg to see how they compare to your model results.
Was the timing of the late check right at the end of the cast when there the fly leg length was quite small? It does not appear to have had much effect compared to the base case.
