37 steps---delayed response

David:  

I wouldn't give the procedural parsing to much thought.  Sometimes people
just need their own self serving angle.  The steps that Yamaha provides in
their class are designed to give an overview and sequence to a comprehensive
regulation process and to help insure that you don't do things in an order
which is counterproductive.  There is nothing inherent in their procedure
that states once through and you're done.  Clearly a second pass, as it
were, is often necessary depending on the state that the action is in when
you start.  Some procedures will influence others and some will not.  As in
all things, common sense (being none too common) should prevail.  While some
people may prefer the just start somewhere and do it approach, the 37 steps,
viewed in this way, would be a benefit to most.

First, I hate to sound like I'm defending Yamaha's regulation effort at all
costs.   Of course we do things first that have to be done first...Roger's
jumping springs, for instance...your entire list of pre-regulation.   I do
know that LaRoy and Yamaha didn't work out there approach thinking we can
leave that out because any idiot knows to bed the keyframe first etc.   

"Then why title it and present it as if it were a linear sequence?  I think
Yamaha is sending a mixed message here that is responsible for an awful lot
of confusion and misunderstanding among piano technicians."   

Just curious...have you ever taken a LaRoy Edwards class?    But explain to
me how the 37 steps is responsible for confusion and misunderstanding among
piano technicians?
