?? Fairness with roll-over win/loss percentage ??

Since I have been watching the stats I noticed the fact of the rolling over of percentage win/loss to the next rounds. My query is to why and what legitamacy does the IPT use this method? Since the players compete to move on from group to group by win/loss over their respective groups(top 2 to 3 from each group moves forward) why does the GLI roll-over from the previous round? The player made the cut on the previous round either by totally dominating or by just making the cut. I am wondering on the fairness of the system. Point in case---Alex P. lost his first game in round 4 however all the other players in the group maintain a lower win/loss percentage. I guess what I am getting at is that you can go undefeated for 3 rounds than fall asleep at the table and muster 2 to 5 racks per each opponent(losing all matches) and still move on due to your roll-over percentage. I think if I was in a group like that and beat every player in the group yet still had the lowest roll-over percentage I would be very livid. Not only would IPT have an earfull from me, but every national media I could broadcast this backwards system I am witnessing.

Has anyone else seen these numbers and wondered why?
 
The three players with the most wins in the current round advance to the next round.

The win % is only the first tie-breaker if two or more players are tied for third place in their group.

Rolling the win % over keeps players who are already assured of advancing to the next round from dumping some games in their last match.
 
I think what he is trying to say is it should be matches won in current round, games won in current round, then cummulative win% and b/r%. Right now it is matches won and then cummulative win%

I would agree with that. If I went 8,8,7,7,7 and lost to a guy that went 8,8,1,0,3 but dominated a weak group fro mthe day before, I don't see how the best player went through.
 
Just a minor point of clarification so that there's no confusion on what KB intended...

You might want to re-read his post. He said Alex P. could lose all five of his matches and if his win % was still higher than some of the other players he would advance.
 
I think the format works as is. Similiar to variance in poker, it will average out in the long run with percentages. The reverse to your theory, is why should a player be penalized if his opponent b&r's the match for a 0-8 score? I like the totalling all percentages for tiebreaker purposes, rather than match games.

Variance will be the equalizer and always averages out. As a player ya got to win your matches, to control your fate.

There are several things that you are misunderstanding.
First, they are NOT using the GLI in this tournament. They are using 1. Matches won per round, 2. Games Won Index (GWI), and for a second tie breaker break and runs. Again, there IS NO GLI IN THIS TOURNEY.

Second, it is impossible to lose every game to your opponents and still move on. If a player loses every match, they have zero wins. Therefore, all of their opponents have at least one win. They can't advance. Even if the player went to the hill every match and lost, they still lose because the first stat that matters is matches won per round.

If you beat every player in your group, you will automatically move on. There is no way to be eliminated if you win every match in your round. The roll-over stat doesn't come into play because your number of match wins is what is considered first.

Last, you said, "I guess what I am getting at is that you can go undefeated for 3 rounds than fall asleep at the table and muster 2 to 5 racks per each opponent(losing all matches) and still move on due to your roll-over percentage." This statement is wrong. If you lose all matches in a round, you can not move forward regardless of your GWI.

Match wins comes first not games won.

Win percentage is used when two or more players have the same amount of match wins.

Wait until the next tournament when the players start off day one with the win percentage they ended up in this tournament.

That's what I thought Jake...as well... but apparently that is not the case.

The way it was explained in an earlier post... each players' Games Won % at the start of each tournament is re-set to zero.

At the end of the year when the IPT is determining which player(s) retain his/her card, the year-end Games Won % may come into play IF two or more players are tied from a money standpoint. The one(s) with the higher Games Won % will be those chosen to retain/earn their card(s).
