What RwyCC value is used for minimal to non-existent braking action described as NIL?

Explanation:
RwyCC communicates how well a runway will grip under current surface conditions. When braking action is NIL, there is essentially no usable friction between tires and the surface. That extreme is represented by the lowest value on the scale: zero. Higher numbers mean more braking capability (some friction, more friction, up to good or dry conditions). So for minimal to non-existent braking action described as NIL, the value used is zero.
