Do tennis strings make a difference?
Strings (tennis)
In tennis, the strings are the part of a tennis racquet which make contact with the ball. The strings form a woven network inside the head (or "hoop") of the racquet. Strings have been made with a variety of materials and possess varying properties that have been measured, such as dynamic stiffness, tension retention, thickness (gauge), string texture (shape of the string), and rebound efficiency.[1]
Seed (sports)
In a tennis event, one version of seeding is where brackets are set up so that the quarterfinal pairings (barring any upsets) would be the 1 seed vs. the 8 seed, 2 vs. 7, 3 vs. 6 and 4 vs. 5; however, this is not the procedure that is followed in most tennis tournaments, where the 1 and 2 seeds are placed in separate brackets, but then the 3 and 4 seeds are assigned to their brackets randomly, and so too are seeds 5 through 8, and so on. This may result in some brackets consisting of stronger players than other brackets, and since only the top 32 players are seeded in Tennis Grand Slam tournaments, it is conceivable that the 33rd best player in a 128-player field could end up playing the top seed in the first round. A good example of this occurring was when World No. 33 Florian Mayer was drawn against (and eventually defeated by) then-World No. 1 Novak Djokovic in the first round of the 2013 Wimbledon Championships, in what was also a rematch of a quarter-final from the previous year. Rankings of tennis players, based on a history of performance, tend to change positions gradually, and so a more "equitable" method of determining the pairings might result in many of the same head-to-head match-ups being repeated in successive tournaments. An example of a seeded 16-team bracket (note that "in each round" in this example, adding the "seed" numbers in each match results in the same number for each match):
In American team sports, the NFL playoffs and WNBA playoffs employ re-seeding, the NBA playoffs and the NCAA Men's Division I Basketball Tournament do not, the Stanley Cup Playoffs used re-seeding between 1994 and 2013, the MLS Cup Playoffs used reseeding until 2018, and the MLB posteseason does not have enough teams where re-seeding would make a difference in the matchups.
