ROFL most of your ratings are some BS! GUYS? For real? No matter how talented you are, it takes at least 2-3 years to develop a consistent single stroke. SO, to rate yourself a 4.5 after ONE YEAR of match plays is ridiculous LOL.
Here's the REAL guidelines:
If you are a total beginner, you are a 2.0-3.0
If you can serve inside the box 15 out of 20 times, or can rally up to 5 strokes in a point, you are a 3.5
Here's where it gets tricky. The jump from 3.5 TO 4.0 requires tremendous effort and hard work. IF you can ace a couple times in a match (against SAME LEVEL PLAYERS), hit about 5 backhand winners and 5 forehand winners, have a KICK/SPIN in your second serve, or can last up to 15 strokes in a point, you are a 4.0
FOR 4.5 - You have either played a DIV II or III varsity college tennis (in some cases, lowly ranked DIV I colleges). At this level, if playing ONE point doesn't get you catch your breathe, running up and down, left and right of the court, or you are able to reach every single stroke from your opponent (SAME LEVEL), then you are NOT a 4.5 player.
4.5 is where the cut off usually is for club, league tennis players. I live in Atlanta, GA where it's hailed as the tennis CITY of the USA and there's only a handful of 4.5 teams competing against each other.
As for 5.0-5.5, you have played tons of challengers and have/had been a successful TOP DIV I college player. You may also be ranked on WTA or ATP at the 1000's. If you don't have a ranking on the WTA/ATP and you say you are 5.0, you are seriously MISTAKEN.
At 6.0, you are ranked around 600-800 on WTA or ATP tours and actually make a living out of playing tennis. You've been taught how to play tennis since you were 5. You are way too good to play or have played for college and you've never joined any leagues or clubs because you are above those. You may rarely get a wild card entry to play @ the Grand Slam levels only to be humiliated on the court. When you get to 6.5, you actually have a better chance at making the top 200-300.
7.0 - YOU ARE a PROFESSIONAL. You have played tennis since you were 4 yo and that's basically all you do every day of your life. Roger Federer is as good a 7.0 as whoever is ranked @ the 100's. Serena Williams is as good a 7.0 as the # 135 ranked girl on WTA.
I myself am a 4.5 and that's 10 years of playing tennis since I was 19. I progressed from losing all my matches @ the 3.5 level and worked myself up to one day winning the collegiate club nationals in 2003 for UF club tennis and also winning the GA States in 2007.
Re-rate yourselves peeps! And, come up with a reasonable rating instead of a delusional one!
