It gets a bit curious for me at this point. It seems "hauling" is not optimized until the stripper guide is perpendicular, or beyond. And the guide could have gotten there via rotation, translation, or both. And... perpendicular to what: the ground or the line hand
lots of well put assumptions in your post!
The problem with modeling fly casting is, that it (the fly casting) is too variable depending on all our different fishing situations.
The haul can be done in many different ways.
If we want the line to run as fast as possible thru the guides, I believe it's effective to move the line hand in one way and the stripping guy almost opposite. Almost, because on one hand it's great to use the rotational speed (angular velocity) we can create for the stripping guide via rod hand and on other hand this requires having to live with more friction between the first guide and the line as when hauling exactly parallel down the rod.
Which technique I prefer depends on what exactly I am after. For sure it's worth playing with both.
I studied the different hauling techniques across many participants in the WC. Made a lot of videos. Fair to summarize there are a) different techniques between the fc and the bc for one caster as well as b) differences from caster to caster.
Of course in the WC we often also have to deal with different winds from caster to caster making it hard to compare.
Imagine this:
Caster 1 feeds his line hand far back close to the first guide in his back cast. That may lead to a lot of line having to be straighten outside the tip.
Caster 2 feeds his line hand less far back having less line outside the tip for a while. Both are holding their line at the same point.
Now you may say caster 1 will have more distance to speed up his line hand on the next fc, but it's not that simple. Caster 2 may slide his rod forward coming from a lower tip position only to then have additinol line slipping out the tip while pulling on the rod-leg by lifting the tip. Both may end up in a similiar set up to start the fc.
There are so many details one can work with, I don't see any model including all this giving an easy answer to what's best in general.
