In the TR Performance By Event reports, Self Donor and Non-Self Donor reports on ANY transaction, and many participants gather cash and then use their own charge cards. Participants that *make an additional gift* during registration is a far more useful metric.

Also 'Donor' in this report is anyone that has made any transaction, which lumps registrants, donors, purchasers, etc. together. Not useful. Make this only non-participant DONORS.
