User 342416, benlynn, is a good example of this effect.
I remember that there were another formula for ...[text shortened]... nts.
That former rule was not all bad, but 30 days was to small. Let it be 100 days, or more.
Obviously, you have to exclude provisional ratings in any algorithm,
I posted this back in '06...
""It seems to me that there are 2 seperate, though similar, problems here.
1) New players joining banded tournies before they rise to their true rating
2) Old players who's ratings have dropped due to T/Os entering lower banded tournies.
So, IMO, you need 2 seperate solutions.
To solve number 2, I'm sure the best solution is to use a rating spike minus a certain number of rating points as their floor. Instead of taking a one game spike as their spike, this rating spike should be gotten by getting the highest average of 10 (maybe some other number: 20/30?? ) continuous games. This minus say 100 or 150 could be set as the rating floor, purely for banded tournaments. Their rating could still drop below this floor.
When they come back, they can still enter banded tournies at their floor rating.
For new players, who haven't reached their correct rating, then they should only be allowed in banded tournies above the rating of their highest opponent in a game in which they won. If they have beaten 1600s, then they are in the 1600+ band until they beat a 1700. If they then get beaten by a 1600 while still rated below 1600, their band could be reduced by 1 band. "
Best solution I've seen, if I may say so myself. The site should be moving towards more automation, not less. Starting the next round of tournaments when the progressors are known simply needs a script. Keeping banded tournies banded could be achieved with an algorithm based on the above system.
The idea is further fleshed out in the following pages.
