Korean City/Regional Div 4 average range of level is TTR1200-1500 or USATT 1500-1800. Some of the top players are higher, but they avoid moving up a level and purposely avoid getting to the finals of singles, so they can be underclassified for the team event.
Park PD's opponent is Div 3, which SHOULD be TTR 1400-1600 or USATT 1700-1900... but this guy is likely 2000 USATT, that is very normal. When I lived in Korea, a certain TT club, which also IRONICALLY wore Orange jerseys, had literally 7 players who were DIv 1 city/Regional level (TTR 1700-1900) but were all classified in Div 3... So if you your club faced them in the Team event 3 vs 3, you would be fielding Div 1 players vs their Div 3 players who were equal level, but getting a 3 pt handicap each game. So you see the gamesmanship the clubs do with their players to win the glory of the team event in city and regional tourneys.
