Mahound appears to be referring to version 2.6 (still in beta), in which you can select folders and/or files to include in your stats, which would allow you to select specific tournaments for inclusion in stats.
However, this wouldn't help. What you want (I think) is to include money, points, hits, etc, from all tournaments, but average the points over all of the tournaments except the satellite and championship tournaments. To do that you'll have to average the points yourself, because to get the proper totals you have to include all tournaments, and the "Average Points" column is going to be averaged over all included tournaments - not what you want.
In the Filter (or Profile, if you're using 2.6), set your Tournament Score formula to:
points
And set one of your Overall Score formulas to:
sum(scores) / (n - 2)
Note this assumes all players play in all tournaments. If that's not the case, you'll probably want to use:
sum(scores) / (count(scores) - 2)
And this assumes that while all players don't necessarily play in all tournaments, all players do play in the satellite and championship. If that's not the case, you've got a much harder problem.
