Question On Reported Windshear With a Wet Runway

A B737 departing on a wet runway will have a reduced V1 due to slippery runway, if there is suspected windshear, SOPs call for an increase in VR up to the maximum runway limited weight not to exceed actual VR by plus 20 kts. I am curious to find out if your SOPs allow the two to be used together.

Thanks

The V1 will be based on a full rated take off with WET performance so the V1 won't change at all when it comes to increasing the VR speed.

Thanks B737900er, that is correct the V1 will not change because of the wet runway, however I have been told that other carriers are not using the wet runway and the correction for windshear together as a combination. This is the reason I posted this to try and get some response from other operators.

Thanks
