"Measurable proportions" is a significant indicator.

What indication, measured by what and by whom, do you have 
that creep is the cause of this, other than wood compaction, 
as I've said, and coils settling, as Ed pointed out?

I think you are, along with most everyone else. Most people 
seem to think that music wire keeps stretching forever, but I 
don't think that's the case. Do they go out every year and 
tighten the cables of suspension bridges every year to pull 
the roadway back up level? Anyone know?

Been looking for real information for years, on a lot of 
things like this.
