Speaking length is on the agraffe side.

I didn't measure the wire size on the (62mm) .  It doesn't matter anyway.
Percentage of breaking strength doesn't change with wire siz.  Only speaking
length.

My 5'4" piano had a speaking length of 58 mm.  The wire size was  .030.
Changing the wire size made no change in the breaking percentage.  It
remained at 83 percent.  I can only assume that the 62mm note would exceed
that.  If you increase the diameter of the wire it must be at a higher
tension to reach pitch, hence no change in the percentage of breaking
strength.  Comprendo?
