A WebmasterWorld thread reports that Google seems to be misreporting conversion data for the Google Referrals product.
The affiliate decided to test out his theory by isolating it to one specific product. The nature of the product he picked was that every conversion would translate to a "non-zero amount." He noticed that the "daily earnings are always a multiple of the single conversion price." That the integer_number is usually less than 1/3 of the number of conversions."
He is not the only one to notice issues with Google reporting wrong numbers in the Referral product.
Is Google skimming affiliates? I.e. skimming money off the top? Would they ever?
