To string a racquet with an 18*20 (ou 18*19) string pattern in 4 knots, same framz size, for similar playing performances :

  • The string-bed stiffness is about 10% higher with an 18*20 string pattern than in a 16*19 pattern
  • to obtazin the same playability >lower tensions -10% (-2Kgs) for each of the tensions applied for a 16*19 pattern 
  • the new reference tension = 21kgs (i23-2kgs) > string in the 8 (instead of 6) mains in the middle at 21kgs > 
  • lower -2kgs = 19kgs for the next 2 x 3 mains > for the last 2 mains +4kgs = 23kgs (tie off the 2 mains' knots) > 
  • for the1st cross and starting knot > maintain the 23kgs for the first 3 crosses > -2kgs = 21kgs for the following crosses 
  • for the last 2 crosses +4kgs = 25kgs > tie-off the last cross string. That's it, finished.

On-court Player/Material Analysis Programs

For tournament level tennis, personalization is preferable, the JET Concept Programs offer :

  • to decide what adjustments are most needed and propose several constructive solutions
  • to experiment various set-ups to evaluate the most appropriate choice of materials
  • to string and test on-court an initial reference set-up of racquet/strings/gauges/tensions
  • to organize a 2nd on-court program to adjust/fine-tune of the initial reference set-up.

The results obtained by the player after the 2ème program of tests/court are generally very positives and entirely satisfying for the player. The overall progress in the level of play during the following weeks is remarkable.
