Vereinheitlichen wäre eine Option. Die Frage ist auf welcher Ebene...
Spielt man als Jugendlicher auch bei den Erwachsenen mit oder Damen bei Herrenmannschaften, hilft aus oder spielt Turniere/Ranglisten oder Andro Cups/Races oder den Sommer-Team-Cup gibt's dann u.U. wieder das Problem mit unterschiedlichen Bällen.
Die ITTF arbeitet momentan 1) 2) daran das zu verbessern/zumindest für mehr Transparenz zu sorgen. Wird aber auch nicht wirklich helfen, wenn man sich so manche abgeranzten Bälle und Tische ansieht mit/an denen man spielen muss.
"2. Ball Bounce on Table (BBoT)
The playing tests conducted in Germany, China, and Japan revealed distinct friction
categories among the four tables, broadly classified as "Slippery," "Stopping," and
"Between." Notably, players easily distinguished differences between tables with high and low friction levels, with BBoT measurements proving effective in identifying these
variations. Participants expressed a desire for more clarity regarding the designated tables for upcoming events. The conclusions drawn include the efficacy of BBoT device in
categorizing table friction, the grouping of approved tables into three categories, the
distribution of relevant information to markets and event teams to enhance transparency
for all players, and the recommendation for periodic retesting over a five-year span to
maintain consistent friction levels, to be incorporated into the manual approval process."

"The higher the friction value is, the more the ball will bounce forward (see figure 22). All 20 ball measurements on the tabletop sample will be calculated to an average result. This average result of the coefficient of friction (CoF) must between 0.150 and 0.350 and will be called as the reference value for any future testing/re-testing of this tabletop. Once the result detected is within the limit, the tabletop will be categorized into one of the friction range groups and published on the equipment website."
Allerdings haben die das nur mit DHS DJ40+*** getestet.
