Does a dry mound affect velocity?

Does a dry mound affect velocity? I’m curious to everyone’s thoughts on this. It seems as though there’s cement on the mound in front of the rubber and there’s a very little bit of indention in front of it. So I’m wondering if pushing off basically cement and a hard dry mound can affect velocity? Thoughts?

The only effect would be based on traction, or lack thereof. You are not going to get more ground force simply because the ground is hard. As long as your foot is not slipping there should be no effect on velo.
