Ric,

Hi David.

Looks like you are getting some different readings this time around.  
One of the problems with Stanwoods approach is the reliance on taking 
really consistant UW/DW readings. Friction and regulation problems tend 
to muck up the picture a lot and it takes a lot of practice for many to 
get consistant readings. Of course consistant UW/DW readings is rather 
alpha and omega to the whole process.  When I was first learning this I 
started taking the same 10 sample notes and measured 3-4 times a day 
inbetween doing other things. I was suprised to see how different each 
set of measurements read out. 

As to the Key Ratio.  A higher ratio key will require more work at the 
key front, but you will move whatever is at the capstan a greater 
distance. This also means that for the same speed of key front movment 
the capstan will move faster (as it moves a greater distance in the same 
period of time). Lower the key ratio and your finger will have an easier 
job of it, but you dont get as much movement distance wise (and hence 
speed wise) at the capstan.

Cheers

I did the numbers again:

             R
#1         6.0
#2         5.8
#9         5.9
#10        6.0
#16        5.4
#17        5.8
#28        5.7
#29        5.7
#40        5.5
#41        5.6
#52        5.7
#53        6.0
#64        5.7
#65        5.3
#76        5.6
#77        6.1
#87        5.5
#88        5.3

Averages out to 5.7

Looks like the bass needs the balance rail shimming...17 note bass.

Is a higher Key ratio mean better or worse leverage?    5.5 vs 6.0
