Hi Lasse

Gordy was kind enough to provide me with the corresponding files. I do knot know exactly the video sources.
In your case it is a cast from right to left with a marker on the line, close to rod tip.

This is because Lasse has long legs and short arns. We measured our respective reach a few years ago and discovered I was a baboon.
It's an exploration; bring a flyrod.

I also have short legs dude :D

I was just curious about measuring, even for a baboon Paul hasn't got a meter more reach, so I was thinking it might have been a cast with a significant step or steps...

How do they compare if we use FFI definition for stroke length :p

Hi Daniel

Which of the hand paths did you use? Do you know if anybody checked to see if Paul was a throwback?

Start to finish 2 1/4m sounds right to me (includes Slide). It’s Lasse’s cast that is the surprising one.

It depends how far apart the branches are:

I used a model of Paul's hand path, but the comparison is difficult since I cannot exactly tell when the translation and the rotation starts for Lasse's cast. For Paul rotation starts at about 1 meter from the origin in the x direction.

It is interesting to see how we can speculate on something for which information is still lacking. It could be like that:

Hi Daniel

Then it's most likely this one:

It can’t be that one Lasse. Whatever produced your graph had tiny T-Rex arms
