Using Brecoflex belts and FIRST spec carpet, the traction increased by DECREASING the amount of contact area! This appeared to be because the impact of additional deformation of the carpet due to higher local pressure was a higher order effect than the additional quantity of "nubs" interacting with the carpet. It threw our F = mu*N + nu*A hypothesis out the window. Stay tuned.

Oooh. Bring it on
Your daughter can have a white paper on her hands. I'm looking forward to reading that, and it's just in time, too.
Are you sure that there aren't characteristics of the belting that may be contributing to that discovery in ways other materials might not? Do the results hold true for the wheelchair wheels, for example?
