I don't understand the basis of the scoring system you are proposing. This
still looks like it gives small projects a share of the ranking that is too
large.
A person that has 1000 points in a project with 10 users and 10000 points
total would be higher rated than a user that has 1000000 points in a
project that has 10000000000 points and 100000 users.
If points are equal across projects, this weighting seems absurd.

Re: [boinc_dev] credit goals
I've recently been playing about with various simple algorithmns within the
stats to see what various criteria once summed up show in place of combined
credits.
In an attempt to offset individual projects credits swallowing up smaller
projects I've based it (for now) as
points = (user credits / total credits in project) * total users in project
After running this algorithm through my database and then summing for total
'points' it gives the top 20 users as follows (rankpoints2)
I include the data for their current total combined points (metric1) and
another points scoring mechanism (rankpoints1) purely based upon relative
rank positions exactly how they do it at the DC-Vault. However I think the
rankpoint2 scoring works better.
It clearly shows the massive contribution to boinc of the german grid on
Einstein (13% of the total points there)

I'd welcome any discussion on this, not sure if it would be feasible to
work
into the BOINC framework itself..
