TCR calculation question

[thesidster]

Is TCR calculated on the basis of all tournaments or the most recent N tournaments ?

 

I ask this question because if it was on the basis of all tournaments, it would not

be as sensitive to recent activity as it obviously is.

 

So what is the number N ? 100 ?

 

Enquiring minds want to know.

Rolling 60 days. Some tournaments don't count (either way). Some tournaments (with robots, where dropping doesn't disadvantage anyone) count +1 if you finish, but no score if you don't, so they're a good way to bump up your average in cases where the drop was in fact no fault of your own (massive storms yesterday taking down most of a state with little warning, for instance).

 

Enquiring minds can search (giving this credit, because BBO Forums search has a 4-character minimum, which is really annoying when looking for almost anything bridge related, but isn't changeable by BBO people), using the following format on your favourite google-alike: "site:www.bridgebase.com/forums TCR"
