Walter & Group............
the idea of the rate of change of the rate of
change of position (i.e. acceleration). If it's easier to think
in terms of increasing, constant, or decreasing
acceleration, then I don't have a problem with that but
any time you have a non-constant acceleration then
you can determine the rate of change of the
acceleration.
I have to agree with Bruce's statements,
especially:
****And this is certainly
where most casters end up, but it is not the
ideal. Obviously, the top
casters are that due to a lot of practice and
natural ability. The fact
that only a small % of casters are able to
achieve near constant
acceleration doesn't mean we all shouldn't strive for
it. Few golfers have Tiger
Woods swing either (and his club angular
acceleration is very constant
I'm sure), but most would like it....
The only way to
get better is to practice but practice alone won't make you perfect or near
perfect.
You also have to know what to improve and how to
improve it. Bruce and Noel have given us some
great insight on the what in this
case.
Cheers
Walter

From Mac Brown: -
I like Steve's explanation which is back to what I referred to earlier -it
is non-sensible to say it twice. Some other good posts from David and Phil. I
realize the necessity for simplicity when teaching a newbie and this discussion
would not be happening in that example-except this study group is focused for
instructors. Hence, the term constant fits already and it has been used in
elementary math/physics classes for years now. If we try to reinvent something
complex like mechanics (kinematics) with too much simplicity, where will it
leave the teacher who is supposed to teach? It will keep them stuck from aiding
or advancing other casters in the long run as they progress along their way.
I have been a foe of rules, over-generalized statements, etc... for a
long time now because I think they can be dangerous in stagnating ones learning
curve along their journey of casting. In fact, I believe this so much, that as
soon as someone wants to make up a rule, I am already thinking of how to prove
it wrong with a rod and line. If I succeed in doing so, the rule must have a
fault because the real world defied it. Mechanics are simple and clean
cut. They do not start with one set of parameters and then later change to fit
the journey-they are what they are all the time. Think of all the sports out
there which hold true to the foundations of what was taught in the beginning
-does not change when it is advanced. They remain the same. I realize having a
string attached to a lever can easily lead to frustration for newbies. If we are
truly interested in lighting that spark of enthusiasm for their journey-we must
not limit the process. For too many years casting has had this allure of mystic,
often ego based instruction, that it has damaged the sport much more than aided
its progression. I think that is more in the past now because their is a
willingness to share and explain, rather than the approach of guarding them like
top military secrets. The average caster is also much more advanced than in
years past because some of these barriers are coming down.
I had this discussion a while back with a client that was a quick
learner. He had some problems with getting too much slack in their
deliveries in the early stages which gave them long floats-hence he caught more
fish as a newbie than when he progressed to a more advanced caster. This is
common for budding casters. He had some problems bending the rod to the amount
of line being tossed. He read all the rules and video like the gospel,
learned to throw more of a SLP, tight, fast candy cane loops. Result, he
practiced it so much that it became his routine on the water and the leader
began to turnover straight as an arrow all the time. His muscle memory learned
what he percieved he should be doing all the time-hence there lies his problem.
Result, now he looked much better, like the suv, aspirin commercials, etc... but
he was having no hookup days. Now it took a bunch more practice to learn how to
intentionally put slack, curves, etc... into the stroke. If he had not abandoned
those early rules, he would have remained stuck.
The post has made all of us think which is a benefit for all. We do not
want to reinvent things that are already learned. I think of casting more like
art/music. It would smash the creative process to follow rules. I do appreciate
the manner which someone like Dr. Liming used kinematics to explain it
to me the how, why, when, where, type things of my own casting. Once I
understood his point of view, it was like a light bulb went on for explaining it
to others. His point of view took me a while to understand, because he kept
feeding me more literature on basic kinematics at the time. Before meeting him,
I could perform certain casts that I would struggle for explanations of why the
results occurred. It aided in my growth of understanding what I could already
do! The benefit was that it has since lead me down a road of new discoveries
because "what if" seems to always arise. I think the analyzer is exciting new
territory for aiding the smooth factor of constant acceleration.
Cheers,
Mac

Comment: Yes ! The frustration derives from having a
string at the end of a FLEXIBLE lever .
The analyzer has given us a real tool for measuring what happens for the
most important part of the cast at the butt section of the rod. The video
analyses are useful for telling us what happens at the tip. The line tells
us the result !
