I replied to you via PM, but I'll repeat the essence of that reply here because it might be of interest to others.
The credit process is a little bit convoluted, and goes a bit like this:
* PRPNet server for the port you are crunching creates a WU and sends it to your computer.
* Your computer crunches the WU and returns the result to the PRPNet server
* The PRPNet server does whatever kind of validation it does, and adds an appropriate number of points into its database for the account name and email address you used.
* On a periodic basis, the PRPNet server dumps its user table into a publicly readable file that can be used by third party statistics sites.
* On a periodic basis, the computers run by Sysadm@Nbg read that file (and lots more like it from the other ports), and incorporates those statistics onto his website.
* On a periodic basis, roughly once a week as time permits, I go to that website and pull all the cumulative PRPNet statistics into a spreadsheet. The spreadsheet is used to calculate, for every user, how many credits have been earned since the last update. I then feed those into the BOINC server.
Depending on the timing of those three tasks that get performed periodically, it's possible for there to be a substantial delay. For example, if a port is down, then its stats file won't be written, or won't be read, or whatever, and it may take an extra week for stats from that port to make it all the way through the process and show up in your BOINC PSA totals.
BTW, by far, the most time consuming portion of what I do is to figure out what BOINC account to use for first time PSA participants. It's not sufficient to just match usernames because there are many username duplicates in the BOINC database, so I do the match on email addresses. So make sure your email address is correct in your PRPNet configuration!
