Thanks. Yes, I know what they are called, but why are there so many matches each day ? And players going against each other multiple times a day ? The table tennis leagues I know, the teams have one match/round per weekend (or maybe two, not sure). A team has 3 players and they play:

TeamA1 – TeamB2   
TeamA2 – TeamB1   
TeamA3 – TeamB3   
TeamA1 – TeamB1   
TeamA2 – TeamB2

These russian/ukranian guys play like crazy for days already. There is like 80+ matches per day per league. If the season goes for some months, this is quite a lot of matches
