Ok reason I ask if this is also applicable to Improved Climb is that last week I checked the TOW between a WET runway and a DRY runway and for the same Runway, same Temperarture, same QNH, same Slope I had a WET TOW of 77 Ton and a DRY TOW of 75,8 Ton.
Now as I read the rule I am limited by the DRY runway TOW of 75,8 Ton on a WET runway.
