? The OP's vid? It's a very nice looking serve. wild vid estimate - 90. I haven't seen anything here with "radar verification" save the blog with the guy's posted first serve speeds of D1 players barely breaking 100. (edit: I did see the arcade like stuff - if that's the "verification" we should just stop discussing....) Again, no doubt 100+ is possible and done by a small percentage of rec players. The challenge of impossibility was 120+. As far as competency, I'm no leed. I do have a gun. Playing around with it and it's easy to get a feel for *real* speeds. (And rec players by and large are coming nowhere near 100; small college guys I hit with do get in mid 90s.) Watching a vid and guessing is much more inaccurate.
