Joe, Joe, Joe! David means to use his overpull amounts as a percentage =
of how flat the string is - not that percent of total tension!!!

Let's say a tenor string is 20 cents flat - a 25% overpull would mean to =
pull the string 5 cents sharp. That shouldn't break too many strings.

  On small spinets, reduce the numbers by 5% each.   Do unisons as you =
go."

  David,
  I must take exception to this technique! Although, it will work most =
of the time on most Olde Uprights and Grands, there is always the =
exception. This technique is archaic, to say the least. There are better =
ways. The 32% in the upper treble will most likely get someone in a =
world of hurt! Most strings, in that area, are already at/above 50% of =
their breaking strength!!! You raise it another 32% and strings will =
break, IMO. I've done some studying on the subject and wrote an article =
for the PTJ, in Dec. 1999.
