I was reading some of my teams' old news posts and came across this.

Limit is up to 5,000 now from 2,000.

This must have been during the inital beta.

7 years later there are a few more than 2,000 or 5,000 that PARTICIPATED (Past or Present).

Boincstats says 90,654.

Anyone who participates, past or present is a participant.

Participant:
One that participates, shares, or takes part in something.

See the Statistics page and click the Top Participants link.

The database here will only show 10,000 and I could not find a list with users with credit avove 0.

And yes the boincstats active has some kind of period and i don't know what it is either. For instance it always shows in the 1100's for my team, yet the last day contributors is between 750 and 800, so even the active number is not acurate as some may have tried it only once in that period and are not currently active.


But back in 2004 I think the registered were more active. If I remember that 2000 limit had been raised from only 1000 about a week or less before. It didin't take long for that many to sign up. Then I think they reached the 5000 within a short time, less than a month and at that time active participation was very high, like 75% so they were more active.

There were only 4 projects back then.

Your definition of participant uses the present tense and therefore excludes those who aren't participating now. Those not participating now are not participants, they're past participants, has beens, the dearly departed or whatever you like. If it said "one who participates or participated..." then past participants would be included. Just my interpretation of the definition, YMMV.

It's easy to get a count of participants with RAC > 0. Put the following URL in your browser

http://lhcathomeclassic.cern.ch/sixtrack/top_users.php?sort_by=expavg_credit&offset=2400

That will take you to offset 2400 in the list of Top Participants sorted by RAC. Play with the offset number and you'll see that somewhere between 2400 and 2500 the RACs changes from 1 to 0. You can narrow it down as close as you want by fiddling with the offset.
