Wet tires temperature

Do the wet tires need to get up to temperature, and should you set a hot pressure when coming off the track?

Ive tried a lot of pressures on the Vegas, and can’t really figure out what hot pressure they should be at.

I usually run about 1,2-3 bar (18 psi) hot pressure. Is that too low or too high for the Vega W5 on a typically wet track?
Or am i not supposed to set a hot pressure, and just concentrate on the cold pressures?
