Call for scaling spreadsheets

[Ric Brekne]

Ron Overs gives

(CovDia^2/CoreDia^2-1)*0,89

for B for bass strings in the spreadsheet he posted a while back.  I 
would be really interested in hearing the reasoning behind this. 

Fandrich, and I have heard this many times here as well, underlines that 
the whole Inharmonicity bit with regard to scaling is to insure 
evenness.  No big jumps from one note or region to the area.  As such, 
strikes me that it is less important what standard one uses as long as 
its reasonably close.  Relative degrees of overall inharmonicity will be 
seen from scale to scale as long as you use that same standard.
