[GH] From Paul Arden :
Hi Gordy,
I'd also like to pick up on this:
"Until then the tip ring was pulling the line, then the tip ring direction changed and the fly line continued forward due to its momentum. None of the commotion that occurred after that made a positive contribution to the cast; these later events are simply undesirable artifacts."
While the fly line can carry on because of its momentum, it's not going to travel very far unless it forms a loop. It's the tension in the loop that pulls the fly line along and that tension is a result of the momentum change at the loop face. Since the rod tip is pulling the line between RSP and MCF it is increasing tension and therefore is certainly not undesirable.
I would also argue that tip travel from MCF to RSP2 could be considered useful. It's during this phase that we use "pull-back". The purpose of "pull-back" is partly to raise the rod tip, but also to increase line tension.
This is my opinion anyway. I've asked for a second.
Cheers, Paul
[GH] MCF = Maximum counterflex. RSP 2 = the second rod straight position (between counterflex and rebound)

[GH] Paul,
We can also increase tension to help the loop leader turnover faster when we use a "check haul" after the loop has traveled some distance but has not quite reached the point where the leader is still in the fly leg.
As with "pull-back" I think both could be considered useful if used properly.
One could argue that as the caster aims the fly rod at the target or rotates it after loop formation to minimize friction between the line and the guides that this are rod disturbances after loop formation which can be helpful as well.

[GH] Ally Gowans answers Mark Surtees' message :
Hi Gordy,
Mark is correct - after the line is launched the tip ring often continues to pull a portion of line out of the direction of the cast. This is detrimental to the cast because loop formation is delayed and energy is wasted and it would really be better if it didn’t happen but unfortunately it’s unavoidable. That however does not make it desirable.
If Mark has reason to believe that such transient disturbances are beneficial I would be delighted to hear the evidence.
An underpowered “cast” is really a mend following a back cast.
