String Scaling

[robert sadowski]

Dear list,
     I'm restringing a Behr Bros. full upright.  The scale that was on the
piano had two
sections in the middle that had 14 and 16 unisons of gauge 17 and 16 wire
respectively.
a fellow tech suggested splitting up those areas with half sizes to make a
smoother
transition and also make a slight tone improvement -( by decreasing the
tension
slightly on an already tired soundboard).  Any validity to this? I'll
probably rescale
with P-Scale anyway but I'm just curious about the original scale design. 
Does this
seem like an unusually high number of unisons with the same wire?

Thanks to all
