If talking about in-flight calculations...
...we are of course assuming your manufacturer actually provides ALD WET figures. The only ALD WET figures provided by Embraer (E190/175) are for Abnormal and Emergency operations. Contaminated data also exists. But you have to stick your finger in the air for 'normal' wet operations. I add 20% to DRY and it appears to work.
But whatever the numbers are, you must always ask yourself if you are being very wise operating into a place where the LDA is approaching the LDR, wet or dry.
