Here is a vid showing how at the club level they are seriously underclassified.
The lady is Div 7 in her club and the guy Div 5...
OK, I get it, the lady pushes heavy underspin into the net a lot, but her FH drive, her footwork, and her countering are way higher level. She would be a typical Div 5 city male Div player in the amateur syste, One part of the vid says she is Div 6, the other 7. I say 7, because she is getting spotted 3 point handicap, which means 2 levels of Div difference.
The guy, he is listed as Div 5 club... he would eat up a lot of Div 3 city players and spit them out. Let's call dude a Div 4 city ringer, many clubs have several players like this purposely under-classified. In my former city, there is a club where they have SEVEN each Div 3 classified players who are ALL STRONG DIV 1 PLAYERS, so they clean up on team event more often than others, because they were better at sandbagging.
We can complain about how or why such and such system has ringers and underclassified players, but every possible solution to that issue can be defeated by one or more means. The easiest way, which is the most common way, is to lose purposely during the group stage, then lose again right before making finals.
If you enforce a points rating system, like in USA, where players gain or lose ratings points based on level of their opponent's then all it would take is some loses in the group stage of singles... BAM, now player is classified UNDER hiz true level and has green light to go beast mode and win out in team event without making his rating jump up too much... and if it does, then he could always lose in group stage again next tourney, maybe both matches. If the event is combined event, like say Div 3/4 or Div 1/2 (they combine div events if there are not a lot of players in a division to fillout the brackets) then they could face much lower rated player and lose... win-win. Lower player gets ratings points they crave, and ringer lowers his rating safely.
Jeong Young Sik's dad is a legit Div 1 city player, but he uses the singles event as a warmup for team event and ALWAYS loses his group. This does not give him an advantage for classification, he is properly classified at Div 1 city. He simply isn't interested in advancing in Singles events, it is too many matches that could ruin his focus of team event.
Did I forget to add the vid? Would anyone kindly clock me upside my big head for that pls?
