Not quite:
Max acceleration = CoF * g (ft/s^2)
dynamic: .05 * 32.174 = 1.6087
static: .06 * 32.174 = 1.93044
thus the 0-10ft/s times are:
dynamic: 10/1.6087 = 6.2162
static: 10/1.9304 = 5.1802
difference: 1.0359
That's just a bit over a second, a fairly significant difference. Not to mention the fact that preventing slip will improve handling.
