Without following whether every case is correct the general principal 
sounds entirely reasonable. One could arguably achieve much the same 
results by using an ohm-meter on a suitable range. You method is 
better suited to ANYONE as it removes the need for a meter :-). The 
meter does allow an easier discrimination of the versions with a 
common point.

I wondered whether a meter set to volts might be useful, but 
standardising the finger flick speed needed to produce the test 
voltage may be too hard.

Steppers with no dc excitation would be better suited by the ohm-meter 
method.
