Javier, the rule is in place not necessarily as a deterent, but as a way to keep teams in contention from benefitting from a full team default. There are always a few teams in our local league (usually men's teams) that defaut full team matches at the end of the season if they are not in contention. The teams that they default to should not benefit from the default. The round robin is really not complete if there is a full team default in the standings. The idea is to play all of the matches. That's why the team results are removed from the overall standings. No one benefits, but no one is hurt. And again, if all teams in contention played the team that defaulted, then you leave the overall standings alone. TennisLink has a feature that DQ's a team from overall standings but leaves all individual matches in TennisLink.
I can't figure out a good way to deter teams from defaulting full team matches at the end of the season. Quite often the captain makes every effort but they can't get anyone to play. I don't think the captain should be punished. Every situation is different, but many times the captain is not at fault, and many captains are very dedicated and want to do the right thing. They can't always get their players to cooperate.
Im not sure how it's fair if you dont count the match either. (how is it fair to the team receiving the default, it's not their fault the other team didnt show up?)
Unless you guys then go by percentage wins or something, but if you are missing a match in the standings otherwise, you will technically lose 1/2 a win.
In our league it would be worse because individual matches are what counts, and we'd lose the ability to win 5 matchs (and lose 2.5 matches in the standings).
If they are not thinking of things that are a deterent then they should be, instead of just worrying about which team is going to win. Defaulting matches does far worse things to most teams then that. (wasted court time, someone doesnt get to play)
Most of us sign up to play tennis, not to sit around and win for free, so in any league it's not desirable at all to have defaults, and if you have them all the time, you tend to lose interest.
Plus if you had a big enough penalty, you might avoid some defaults, and then you wouldnt have to worry about the standings as well.
