I still have no idea what is going on here really
I don't even know what would make people get out.
Again.. about scores:
you pick players in each match in post 4 right?
For Day 1, in World Group matches, every right pick gives you 10 points. If you do a wrong pick in Russia vs Serbia, for example, then you cannot make picks in this confront in the other days of this phase.
You get it? (point system here -> Suicide Tennis - Davis Cup 2008
Your nation gets out of the tournament if your score is lower than the team you are playing against. The score is calculated the following way:
total amount of points from team players divided by the number of players of the teams.
As said in the topic in Suicide Forum, you just cannot repeat your pick in each phase. eg: if you pick Federer in Round 1, then you can pick him in QF.
