Expedite Rule and Choppers in the last 25 years
I have been watching table tennis for a while now, and for some reason I can rarely remember the expedite rule coming into effect except in the last five or so years, mainly with Hashimoto and other modern japanese choppers.
Looking at the 2000s and 2010s, defensive players like Kim Kyung ah, Park Mi-Young, Suh Hyo Wan, Wu Yang, Han Ying, I can't remember seeing expedite rule applied very much to them, with a third official counting points. Is there a reason for why it is more applicable now, or am I remembering incorrectly and expedite rule was used in their games as often as it is for modern choppers? Did those older choppers just attack more often or were attackers back then worse at returning chops and different spins or were good enough to end the rallies faster? Or are choppers today like Hashimoto more consistent and better than earlier choppers, and chopping longer before counterattacking, while attackers can loop back consistently but not finish the points quickly?
Maybe the ball change in 2014 also is relevant to this, but the ball changes generally made it more difficult for choppers.
(I also don't think I've seen it applied for Joo Se-Hyuk's matches or Ruwen Filus, but men's game is usually faster and shorter points so that makes sense the games aren't as long.)
The expedite rule in its current form has been the same since 2001, with a minor change in 2010.
