Traffic generated from internal sources should NOT be used in determining the profitability of a PPS program. The reason www sales are calculated is because of the high visibility of the sites from being in a program, you get return customers and SE indexes from a lot of links that is in essence 'free'. www sales calculate a portion of the additional income category which include:

www sales
exit consoles
members upsells
mailing
other advertising avenues

I hope that helps
