That's a pretty big swing, it could be 110 at times. Not many of us carry around radar guns in our bags. I remember a guy at my club, about 20 years ago, who bought one and was generous enough to clock anyone who wanted to.
The BEST SERVE is not necessarily the fastest. Fed and Pete don't have the fastest serves on the planet but win a lot of free points. At their level it's getting into their opponent's head, hitting all the spots (down the T, wide, into the body) and having all the spins, (slice, top, flat), keeping the receiver off-guard, guessing, leaning the wrong way.
If you're young, athletic, motivated you can improve quickly. A freshly hatched beginner can go from 3.0 to 4.0 in a year if they work hard--if they forget about blasting the ball out of the park and keep it in the lines-- they can win a lot with gorilla tennis. He could become a 4.5 in a few years IF he gets really good coaching on all aspects of the game, technique, strategy and tactics (and he doesn't discover girls).
