for me hauling is all about pulling the line thru the guides. I can do this a) by moving my line hand only, b) by moving my rod hand only or most likely (and best) c) by moving both hands in a way that the lowest guide and my line hand gain speed away of each other.
Let's have a look on c), since this is what I use in fishing.
I believe, that my rod hand plays a huge part in making the line run thru the guides since I have a short part of my fly rod available to speed up the lowest guide. Now AFTER the lowest guide has hit max speed, the rod tip is still accelerating due to further straightening of the rod. I don't think I can in any way position max speed for the lowest guide close to RSP1. There has to happen ca. 2/3 of rod straightening....
In that regard I have no clue how I can position max hauling speed (max speed of the line thru the guides) such close to RSP1.
Maybe you understand the haul as just be done by the line hand and only refer to line hand speed? Please help to understand those figures.
Reading this thread reminded me that before starting a discussion it might always be very helpful to define the terms in use.
