Harvey.....
You are right when it comes to teaching new and early students......even students at an intermediate level. One reason that Lefty Kreh has been so successful in teaching is that he uses plain simple language to get his points across.
The concept of SLP of that rod tip is of great importance to these casters......and erudite definitions won't help there, at all. Reaching into our bags of tricks to have demos which get that point across is something we should be able to do.
One reason to have usable definitions is so that we can discuss fly casting with one another while remaining on the same page......so we're all talking about the same thing.
Definitions can run the gamut from those which are simple and easy to understand, but not strictly correct, to very correct ones from a physics/mechanics standpoint. Those scientifically correct ones may well not be truly usable if most of can't understand the details, especially those which require some advanced mathematics for completion. These only serve to confuse students. (and perhaps us as well.)
The most difficult thing is to come up with a middle of the road approach which I see as definitions which are reasonably correct yet plain and simple enough that most folks can readily understand them. This is a bigger task than you might think. The engineers, physicists and mathematicians will be able to criticise on the fine details, but that's OK..........we understand that.
In coaching Master Candidates, I have to go beyond the simpler forms of definitions, because they are at a level which allows them to question the details. They should do that as they go to a much higher plane of understanding of fly casting mechanics. That helps with the development of new and very usable casting techniques for fishing as well for teaching. Their depth of understanding will be challenged as they take their MCI exams.
This very depth of knowledge will be even more valuable to them as they go on to test and certify others.....because it gives them understanding of the various ways candidates for both CCI and MCI status will explain and demonstrate the various tasks at hand rather than relegating the accepted answers to those as written in texts and as, "standard" in various discussions.
This takes nothing away from the marvelous casters and fly fishermen who do so well as they fish, but have no interest in teaching. They don't need the, "how" and the, "why" of it all......they just DO IT.

hi gordy- your terminology of the casting arc being" the angular change in the position of the butt section of the rod from the beginning to the end of the stroke" is certainly correct. however, from a demonstrative perspective of teaching a new student, would'nt it be more of a visual aid to a new student to focus on the rod tip movement in demonstrating SLP vs a 180 degree arc to show what we mean by " casting arc" rather than looking at the butt section of the rod and " trying " to visualize this movement. the same rationale would apply if you were drawing a picture for the student.the movement of the tip is much more noticeable than the movement of the butt section.on another subject, i've read with great interest comments by various members of this site advocating the replacement of the definitions of many casting terms with subject specific medical/scientific terminology. i remember gary eaton saying that if you take a new flycaster, they do not know the terminology and this would be an opportunity to teach them a new language from the start(not a direct quote,gary.). he is absolutely correct,but let's look at this from an industry perspective. could this tend to put the FFF and it's ideology out on the fringe of the flycasting world? by this i mean that there are many more flyfishing guides out on the planet who are not MCI/CCI instructors. many of these people are very competent casters and fishermen, although not FFF certified. if we start to define terminology outside of the main stream of what the majority understand casting terminology to be, do we place ourselves at some risk to the rest of the flyfishing community? when i taught last summer, my experience with beginning casters was that they wanted to learn as quickly as possible how to cast 30 feet or so, but they did not readily grasp what i consider just to be mainstream terminology ie. SLP,rod arc,stroke length( please note: they did learn the concepts if not the language).your thoughts and those of other members of this site would be appreciated.harvey
