Others have already expressed my preference, but I will add my vote. Show us the numbers!!! Then tellus what they mean. My right brain is really fighting with my left brain. Pictures go a long way in describing the forces that are being measured, numbers allow me to evaluate options. Having a BS in Computer Technolgy (a form of engineering), I can appreciate the composite number you talk about and agree that it too would be useful as long as it is explained in terms that everone can understand and realize what it means.

Great work! Good luck with the presentation!
