[CAUT] How long to stabilize??

[Andrew Anderson]

Speaking from an observational point of view without carefully  
measuring; it seems that the opposite swing of the outside unison  
strings might be related to unequal string lengths between tuning and  
hitch pins.  Seems to me that this is one of the stated reasons for  
single string unisons a-la Bosendorfer et al.  Having a little  
experience with Bosendorfer, I am not certain that this holds up under  
scrutiny, comparatively. The opposite would then be true of uprights  
as well and I do note the swing in them, some more then others.

Maybe someone has already investigated this and can lay these  
questions to rest... ?
