Just one point to always bear in mind when landing is that the amount of runway behind you at the point of touchdown is of no use.
Airmanship still plays its part once the numbers are crunched.
Also, grooving makes little or no difference to grip on a wet runway. Its purpose is to facilitate drainage and adds only a small amount to the texture of the surface depending on width, depth and number of grooves per metre.
Any doubts? Go to CDG where the runways are not grooved.
