Kein Praxistest, sondern reine Simulation [1], auch nicht mit 17,25 cm, sondern nur 16,25 cm und 18,25 cm Netzhöhe gerechnet, aber die Ergebnisse sind interessant.
"A clear influence was visible for the 40-mm ball upon increasing the net height. For smaller initial and end velocities of about 10 m/s, a reduction in the number of successful trajectories showed up, being equivalent to a slowing-down of the game. For very low velocities, the impact of the air drag was not yet important, resulting in a larger number of successful trajectories. As a new result, the importance of stronger sidespin for the cases of higher nets was identified, which would change the characteristics of long rallies in table tennis. For these cases, not only are reduced velocities important, but the tactical possibilities will be modified by reducing the number of spinless short trajectories. The strong reduction in the number of successful strokes was linked with rather small top spin components *y, but rather larger sidespin components *z. This means that the game will not only slow down, but also diagonal play with longer reaction times for the opponent will get more important than fast parallel balls. One can also expect from this longer and more attractive rallies. However, the characteristics of the game will change strongly, because the possibilities for successful trajectories are limiting technical and tactical alternatives, reducing especially the influence of service."
Allen wird's mit Sicherheit nicht gefallen, ausprobieren würde ich's auf jeden Fall, da ja anscheinend Spin wieder etwas wichtiger wird.
