Two more for you > how much they roll the surface, and how much direct moisture they allow onto it. These two things have more
impact on the bounce height than most changes made to the grass.
Moreso, the amount of indirect moisture getting into the ground can only be managed to a point - the humidity in the month leading up to the tournament is the major factor here.
