[QUOTE=FlightDetent;9535569]Reverser is not taken into account (regulatory requirement) on dry runways.
But when you do the landing distance calculation the table has reverser column.
[QUOTE=FlightDetent;9535569]Also. you need to apply, I think, DRY/WET check, which tells you to disregard any wet runway results if they come to a better figure than those calculated from dry.
DRY/WET CHECK is done for take off performance as the FCOM says in the take off performance section due to 15 foot vs. 30 foot screen height for dry runways.
QRH does not say doing dry/wet check for landing distance calculation, though.
