2) in a period of time and over a variable distance determined by the stiffness of the rod, the weight of the line (and rod) and the speed of forward acceleration (determined by the angler) the static system is transformed into a dynamic state, and eventually a stble dynamic state. In the beginning 100% of the force is consumed in flexing the rod and the line is only beginning to move. In the end, the force of acceleration reaches a constant AND the rod has flexed to a STATIC stiffness such that 100% of force is translated into line acceleration.
3) Hidden assumption: The issues of rod stiffness, taper, and rod swing weight will vary the DISTANCE necessary for full loading. For a given rod length, differences in the force/acceleration applied, and for different line weights, those issues of stiffness, taper, and swing weight will be felt here. But those issues will not themselves determine the final configuration of the next static state. It may take longer with one rod than another…but given enough room….the rod will load fully to a flexion configuration determined by the maximum, stabilized FORCE and the given mass. ONCE FULLY LOADED THE CASTER FEELS ONLY THE TOTAL MASS BEING ACCELERATED (line + mass of rod tip) through a non-flexing, unchanging, essentially rigid stick. All issues of taper disappear both from feel and mechanically. Issues of swing weight, from then on through the next phase, would be indistinguishable in feel from a slightly lighter rod with a few grains heavier line. Mechanically the issues remain to be dealt with.
Fig 2: Two vastly different rods in terms of stiffness and taper with an equal static force flexing to an approximate full load and advanced to the same position tip point). This point would be the end of the loading phase and the beginning of the acceleration phase.
