The Coman Tiebreak Procedure What is it?
The Coman Tiebreak Procedure is the same as the present tiebreak (set or match), except that ends are changed after the first point, then after every four points (i.e., after the 5th, 9th, 13th, 17th points, etc.), and at the conclusion of the tiebreak. The scoring in the Coman Tiebreak Procedure is the same as a traditional set or match tiebreak, and the procedure for playing the Coman Tiebreak is the same as a set or match tiebreak. For example, if the Coman Tiebreak Procedure is used when the set score is 6-6, the player whose turn it is to serve shall serve the first point from the deuce court; after the first point, the players shall change ends and the following two points shall be served by the opponent(s) (in doubles, the player of the opposing team due to serve next), starting with the ad court; after this, each player/team shall serve alternately for two consecutive points (starting with the ad court), changing ends after every four points, until the end of the tiebreak game.
When will it be used?
USTA will use the Coman Tiebreak Procedure at all USTA League Region and Section Championships for all set and match tie breaks. Use of the Coman Tiebreak Procedure is encouraged during local league play.
Principal Advantages
1. Fairness - By changing ends more frequently, the effects of the elements (sun, wind, etc.) are distributed more evenly between the two opponents as opposed to playing six consecutive points before changing ends.
2. In doubles, the server will always serve from the same end of the court, rather than having to serve from both ends.

How much voltage should be in 2pole circuit breaker?
In America, a 2-pole breaker is controlling 240V. 120V per leg.
What happens when a players pants fall down during a game of tennis?
In the event of a "wardrobe malfunction" during a USTA or professional tennis match, the current point would continue to be played until one of the players has won that point. Generally speaking, the player so affected would be given a brief amount of time to quickly change clothing on the court premises. However, if the player required a long time, as might be the case if no replacement is within easy reach, then the player would be granted a reasonable amount of time to obtain/change clothing off the court, per ITF/USTA Rule 29.b (n.b., in a professional match, a court official would follow the player off the court, to ensure that no coaching occurs). For further information, refer to the USTA link, below.
How many watts can a 20 amp breaker handle per hour?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
How much do basketball players get paid per point?
5,000 per point
How long does it take to build up calouses on your fingers when learning guitar?
You will not get callouses on your fingers until you play to the point they are sore. When they are sore, play anyway. After a week or so, they will have calouses. The longer you play per day, the thicker the calouses become.
Does a double-pole 30A breaker pull 15A per leg and if so why can't 14 gauge be used since 14 is rated for 15A?
A double pole 30 amp breaker can pass 30 amps per pole, therefore #10 wire should be used.
What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
Number of waves that pass a point per second?
The number of waves that pass a point per second is known as frequency. It is measured in hertz (Hz), where 1 Hz is equal to one wave passing a point per second.
Is it safe to have two black wires two white wires and two ground wires on a single breaker?
No, it is not safe to have multiple wires of the same color on a single breaker. Each breaker should only have one wire per terminal to avoid overheating and potential electrical hazards. Consider installing a subpanel if you need to connect multiple circuits to the same breaker.
How many 20amp outlets in commercial building per circuit?
All depends on how big your main breaker is and what size wire you are using,one 20 amp outlet needs #12 wire not more than 50feet away from main breaker
Looking for a basic standard type answer to how many circuit breaker amps are needed per motor horsepower on 3 phase?
The main breaker is not based on the HP of the motor it is based on the FLA of the motor. Many different motors have different characteristics and all of the different motors have different amperages Once you have the amperage of the motor the breaker is 250% times the FLA of the motor.
Definition for time current curve?
It is the relationship between current and time on a circuit breakers opening. When the circuit breaker needs to open in given "windows" of amps and time. They should intersect on the curve to indicate proper circuit breaker functioning. The timing and current value should coincide with each other, per manufacturers specifications. Each breaker differs.
