leverage and touchweight

To the list,
I am a high school student who had made a computer automated device which 
measures the Active touch depth (key dip minus aftertouch)of all 88 keys of 
a piano action in less than an hour, and calculates the leverage from this.

The device takes 3 samples of each key.  If there is a deviation of more 
than .001" it takes three more samples and averages the numbers. It also 
takes the touchweigh of the action. This information is collected and 
graphed so the information is very accessible and easily saved so a record 
can be kept on the history of each piano tested and worked on.

I am competing at International Science and Engineering Fair in San Jose, 
California next week and I need feedback from professionals in this field on 
the importance of these measurements and how useful this type of device 
would be to technicians who rebuild and or regulate actions.   I would 
appreciate any responses, as this is important to my project.  Thank your
for your time.

Respectfully,
Doug Condit
