Excluding beginners

Last I knew, it was 10 tournaments in 60 days. Has this changed?

 

There are plenty of open-enrollment tournaments to play in order to attain your TCR. It is also not at all reasonable to expect BBO to look up your attendance record at in-person ACBL tournaments; off-line behavior is not necessarily indicative of expected on-line behavior.

No, he's confusing Board Completion Rate with Tournament Completion Rate. BCR requires 10 games in 30 days, TCR is 10 tourneys in 60 days.

 

Having an ACBL# is no indication that you have a reliable Internet connection. We don't really care whether disconnections are intentional. They inconvenience other players regardless of the reason. So if you have a flaky connection, which causes you to drop out of tourneys too much, you'll get a bad TCR and be blocked from tourneys that use this statistic. But there are plenty of tourneys that have no TCR restriction (none of the ACBL tourneys do).

Why isn't it lifetime? It's really annoying when you use the service infrequently.

Just because you had a good ISP 5 years ago doesn't mean your current ISP is OK.

 

It also would slow down the program that calculates the ratings every day, having to scan back through years of records instead of a limit period.

The program wouldn't scan years of records each day; it would do that once to create two baseline datapoints (tournaments entered and tournaments completed) then add one day's worth to each field each day.

I agree with the former, but surely you know how to calculate a rolling average, barmar.

Yeah, but it's a PITA in SQL, especially since the query has to work for both players that already have an average and those that don't yet.

 

But this is academic. As I said, we have a good reason for only considering recent activity. We want a rating that reflects your current connection quality, not what it was like months or years ago.

 

Please try to understand that these ratings are not intended as an assessment of you, the player. They try to assess how likely you are to get disconnected from BBO, whether intentionally or not. Recent activity is likely to be the best indicator of this. Having a poor Internet connection doesn't make you a bad person, but it does cause you to inconvenience other players.
