Points are calculated using the following formula:
points = 25*N^(0.30103)[(N+1-p)/N]^(2.0107)
where N is the field size, p is the placing.

Here is the entire table of points out to 100 places, now just 201kb.
If you want to go even further, you can read up on the whole points saga at Topica's NCNCA email archive site (look for "Surf City series notes").

Thanks go to Dan Connelly and David Crum for assistance with the formula.
