What does the numeric level stands for in Tennis?
117083
The Numeric level in tennis is a rating system given out by the USTA (United States Tennis Association) to signify (rate) a players ability level.  Its a guideline so others will have some idea of how good you are.  Most Recreational players around the US are in the 3.0, 3.5, or 4.0 rating level.  Players in the 4.5, 5.0, and 5.5 level have several years of experience and usually play or train often which is required to maintain that level of play.  Anyone above a 5.5 level is referred to as Open Class.  To be technical a touring professional has a 7.0 Usta rating level.  There are guidelines for each rating level and they can be found on www.usta.com

An ace in tennis is a single-stroke point won by the server who produces a legal service that his opponent cannot reach with his racket and thus fails to return. By definition, an ace will not occur should the opponent touch the ball in any way, even if the return is illegal.\n\nIn professional tennis, aces are generally seen on a player's first serve, where the server can put maximum effort on power and take more chances with acute placement (usually the corners of the service courts and the centre serviceline). Sometimes a good server attempts an ace on a second serve, but it is risky.\n\nThe most common placement of an ace is a hard flat serve to either the middle or the corner of the service box, or a spin serve out wide such as a slice serve (to the deuce court) or a twist serve (to the ad court).

At lower levels of play, e.g., recreational leagues, the number of jumps varies by the player's ability. The best players (on recreational teams) gets the lion-share of the sets, and thus, jumps a lot more than others. The ratio between best and worst players on the court could mean 25 jumps to zero. Additionally, the offense usually consists of "high outside" sets, with no "quick attack" in the middle, and thus, reduced the number of jumps required to block. \n\n     However, at higher levels of play, the number of jumps varies by position more than ability. The least number of jumps go the outside hitters, both power and weak-side (a/k/a, "opposite"). Their numbers are roughly inverses of each other, for obvious positional reasons. Figure 9-12 spike attempts for power hitters, and 4-7 blocks; the opposite hitter gets the opposite numbers: 4-7 spike attempts, and 9-12 spikes. The lion-share of jumps go to the middle hitters, who (usually) jump on every volley, because they need to jump before the setter sets the ball. Additionally, they participate in every block. Figure they get about 12-25 spike jumps, and the same number of blocks. Hope this very un-scientific answer helps.

I have coached highschool and college tennis, they way most programs work is that you can only challenge two ranking spots above you.  So the most any player could move is two spots.  The way a ladder is established is through round robin play.  That means players are divided into groups according to ability and the members of that group play each other to establish an order.  There are different rules which govern how far a player falls after losing a match.  Some teams have the two players switch positions like player 3 goes to 1 and player 1 goes to 3.  Other programs have player 3 go to one but player 1 goes to two and player 2 is pushed down to the third spot.  These are the most common ways to establish a team ladder or ranking.

There are singles lines and dbles.  Whichever you're playing determines if it's in or out.  No matter which you're playing though if the ball touches ANY part of the line it's good.  You must be able to see a space between in order to call the ball out.  If you have to question yourself or do not know then the ball is good.  Tennis is based on the honor system and that applies to all who play.

The draw is divided into two parts: seeded players, and the rest of the field.\n\nFor Grand Slam tournaments, the field is 128, and there are 32 seeded players.  The seeds are allocated by the ATP (men) or WTA (women) ranking released in the previous week -- except Wimbledon, which has subjective seedings.\n\nThe 1st seed is in slot 1.\nThe 2nd seed is in slot 128.\nSeeds 3-4 are drawn into slots 33 and 96.\nSeeds 5-8 are drawn into slots 32, 64, 65, and 97.\nSeeds 9-12 are drawn into slots 17, 49, 80, and 112.\nSeeds 13-16 are drawn into slots 16, 48, 81, and 113.\nSeeds 17-24 are drawn into slots 9, 24, 41, 56, 73, 88, 105, and 120.\nSeeds 25-32 are drawn into slots 8, 25, 40, 57, 72, 89, 104, and 121.\n\nThe rest of the field is then drawn to the remaining slots.\n\nFor tournaments with 64 players, there will be 16 seeds.  For 32 players, 8 seeds, with the same basic structure.\n\nThere are tournaments with 96 or 48 players (or other numbers), in which case the top seeds will receive a bye in the first round.

While watching the men's final at the French Open today, I noticed that the French scorekeeper used "zero" in place of "love" when announcing the score. This is interesting because "love" was originally derived from the French "l'oeuf" which means "egg", a reference to the egg-shaped numeral zero. The British then bastardized "l'oeuf" into "love". Apparently, the French no longer use "l'oeuf" or even "amour", the French translation of "love", but just plain old "zero".

well, i don't think you need such a thing. whenever problems of scoring occur in the tournament then you don't want to play in it. it's about the integrity of tennis; all people like chair umpire, linesmen, ballboys, scoringboys, players, they need to know the ethics of tennis, otherwise they don't deserve the place in tennis. if you are the event organizer, you might like to try to contact the ITF (itftennis.com) or ATP (atptennis.com) to look for such things.

An extract from Wikipedia\n\nAs simple as this scoring appears, the running score of each game is described in a manner peculiar to tennis: scores of zero to three points are described as "love" (or "zero"), "fifteen", "thirty", and "forty", respectively. The origin of this scoring comes from the (quarterly) stations of the clock, where "forty" was, presumably, easier to say than "forty-five." When stating the score, the server's score is stated first. If the server announces the score as "thirty-love," for example, it means that the server has won two points and the receiver none.

If it is a competition in the case of matchplay then the extra holes are decided before the match starts, should it be level after 18 and the shots are awarded exactly the same as the original 18 ie according to the stroke index of the hole. In the case of stroke play, then the back nine is counted if that is level then the back seven if that is also level then the back five and then three is taken into consideration, if this is also level it is usual to have either a sudden death or three hole play off, if it is still level after the three hole play off the the same three holes are played over and over until an out right winner is found.  If it's a friendly then be civilised after all it is golf your playing and just go to the bar and buy your opponent a beer and congratulate him on managing to stay even with you over 18 holes

The numbers on the balls are only there to help people distinguish their balls from another can of the same brand on an adjacent court. \n\nNumbers on the tennis balls are right under the logo. This is so that when you have, say, 8 adjacent courts and some are using the same brand or type of ball, then there won't be a mix-up of someone's ball sprays onto the other court. Unless, of course, they're both using the same number tennis balls. For instance, if you are using Penn 3s, the court on your left has Penn 1s, and the court to your right has Wilson 3s, you can tell at a glance which court to throw the extra ball to and in turn they can get your lost ball to you easier.
