Sorry I'm not being clear. When a buyers finalizes an order, the funds are released, etc, and she is given the OPTION to leave feedback. If she leaves the site and never comes back, for example, then your transaction count will always be higher than the number of ratings left for you by 1. If your transaction count and number of ratings are the same, then it means all of your buyers left feedback for you. All that being said, it doesn't affect your average rating one bit when someone completes a transaction, but doesn't leave feedback. It's as if the transaction never happened as far as feedback is concerned.
