Answer from Bruce Richards:-
Thanks Gordy, Jim certainly is thinking outside the box with this one!
Unfortunately, the right answer is inside the box! My comments below....

Subject: Re: Casting arc / rotation v translation
Gordy-
I'm agreeing with most of this. However, sometimes differing styles for
distance casting force us to think out of the box. I've been looking at
loading very deep early in the stroke with minimal rotation as opposed to
loading with rod butt perpendicular to the path of hand travel.
*****The will be very little load without rotation. There are only two
motions we make, rotation and translation. Tip motion due to translation is
slow and short compared to rotation and a slow, short motion will result in
very little load.
I'm beginning to think that the most efficient pullers have the strength
and speed to load deep with minimal rotation.
*****Strength certainly, speed; nope, and certainly not enough distance....
The leverage of the length of the rod gives us speed and distance, but only
if rotated. If merely "dragged" (translation) the rod tip can't move
farther or faster than our hand.
Having said that, it appears the balance of rotation is simply unloading
*****I have to disagree whether talking about time or rotation or distance.
In a typical long cast stroke rotation prior to deceleration is 120 or more
degrees. This is followed by a much shorter, faster deceleration that
initiates unloading. Yes, rotation continues for a short period during
unloading, but compared to the time and distance of acceleration rotation,
it is much shorter.
and that the powersnap/ delayed rotation and haul simply adds to
lengthening the stroke by delaying turnover.
*****Without knowing how the word "stroke" is used here it is hard to
comment. Also, "turnover" is usually used to describe how the loop opens,
it's meaning in this context is foreign to me...
I would like to hear your thoughts.
*****I hope you still think that! Hi Jim!
