Mir sind nur diese beiden Paper bekannt, die DHS D40+ und Nittaku vergleichen:
The difference of the stroke effect between two types of new material seamed plastic table tennis ball: a case study of Nittaku and DHS, 2023
https://www.researchgate.net/publica...ittaku_and_DHS
"It can be concluded that both the ball speed and spin speed of the Nittaku 40+ plastic ball were reduced compared with the DHS 40+ plastic ball, with the average spin speed reduced by 3.05% and the ball speed reduced by 2.74% (Table 2&3). This meant that when hitting the DHS D40+ and Nittaku 40+ plastic balls with the same strength and racket, the spin speed of the Nittaku 40+ plastic ball decreased more obviously than the ball speed."
(gemessen wurde allerdings nur Rückhandtopspin auf Unterschnitt)
Comparison of dynamic elasticity between two types of new material plastic table tennis ball: taking DHS D40+ and Nittaku 40+ as an Example, 2022
https://www.researchsquare.com/article/rs-1683743/v1
"Conclusion: Compared with the DHS D40+, the Nittaku 40+ has bigger hardness and brittleness, and the sphere structure is more uniform, featuring better dynamic elasticity stability and rebound height."
Hinzukommt aber noch die Platte bzw. wie unterschiedlichen Bälle mit der jeweiligen Platte funktionieren.
