How to read it

Its interval accounts for the fact that the offensive and defensive halves come from the same fit and are not independent.

What it does not measure

Everything O-RAPM and D-RAPM miss, plus the fact that the penalty is plugged in from cross-validation rather than modelled with its own uncertainty.
