I'll guess that those last numbers will give rwy friction coefficent/braking action:
RRRRERCReReRBRBR
riction coefficient or braking action
* 01…90: Friction coefficient times 100. For example, 37 indicates a friction coefficient of 0.37.
* 91: Poor braking action
* 92: Poor/medium braking action
* 93: Medium braking action
* 94: Medium/good braking action
* 95: Good braking action
* 99: Unreliable measurement
