ERJ 190 landing distance for wet runway

[kuobin]

ERJ friends,how do you calculate wet runway distance ,since there is no publisher data on the QRH?

For planning it's the unfactored distance times a factor (1.917), for actual landings we use the computer programming embraer gives us (EPOP).
Worst case we can use the tables for BA medium or, in case of a lot of rain, the contaminated/standing water table.
