By what difference in slope >2% will an occupied (250lbs) manual WC begin to roll on its own on AC paving with hard wheels?
Is there a tolerance for distance between deviations in % of slope? (consider 4 points of contact with surface) those 4 points may be less than 30 x 48" between the centerlines of each wheel.
