Even if your company says to take the worst condition given by the ATIS, in this case just think that the penalty is from a "SLIPPERY" braking action GOOD.
But if the braking action GOOD is from a DRY runway, this is just something added automatically by the ATIS as a standard set up.
In even more simple terms, the condition "SLIPPERY GOOD" of your computer based performance or paper performance tables doesn't apply because....basically the Runway is not Slippery!
