I agree, it's a very clear way of showing tuning analysis in a manner 
that should be accessible to many.

Much of the data Dickon has analysed so far has come from various 
tuning books which do not record those partials above the nominal, 
but this would be good to do where the figures are available.

I have also suggested to Dickon that, where bells are tuned 'old 
style', showing the horizontal datum line for the hums as an octave 
could be slightly misleading. The fact that the hum notes are not 
two octaves below the nominals does not necessarily mean that the 
bells are badly tuned. More important is that they are in a 
consistent relationship to the nominals throughout the peal.

Well done Dickon!
