Nifty! So it looks like someone is already to take two different 
arrangements of key leading which yield the same BW and read the MOI 
for each.

And if this device is ready (as it appears) to read a key from a real 
action, then it should be no great leap to add a weight to the 
capstan equal to the Top Action Weight and read the MOI for the 
entire lever train.
