Gary's answer to Jim's complex question:-
Gordy,
Being innocent and ignorant I propose -
The rod bend and hence deflection to 8.5 ft from the 9 ft above hand path
loads the rod. To prevent an upward unloading and concave tip path ->
tailing loop, the rod must be roatated under increasing load to stop so
the tip path remains at or very slightly above the ceiling or dome of SLP.
This is accomplished through acceleration that increases tip bend through
butt rotation to stop. The increasing tip bend creates an effective rod
height no more than 8.5 ft above hand height (or not concave tip path)
until the rod tip has rotated through to the stop at a point where the rod
tip is angled the opposite direction (forward?). The rod tip then catches
up, then the rod unloads (straightens) at the stop to it's full 9.0 ft but
angled not straight vertical from the hand but pointed forward the tip may
be slightly beneath the theoretical SLP.
I didn't get all the variations on the answer ...incompatible format.
Yes. This is challenging.

(Your format is, "mime". Ours is html. Any way you can get yours changed ?.....messages should be much clearer if you do. (Folks who know a LOT more about computers than I do tell me so.)
Yes. This is a reasonable answer....but only if you do what most casters do and add rotation at the rod handle to achieve rod arc. As I understood Jim's question, we are supposed to answer it without resorting to the use of rod arc.....in other words, stroke alone with the rod butt section remaining vertical. Putting it another way, could you alter the path taken by the hand to obtain SLP of the rod tip without resorting to angular change (rotation) of the butt section of the rod ?
Jim....Let me know if I'm interpreting your question correctly.
