TPRs are _meaningless_ for a match. Neither the DB matches nor the DF match can produce a valid TPR. For many obvious reasons... The reason is the floor rating. IF you use the +/- 200 formula, then one player could lose 8-0 and only be 200 points lower than the winner. That's wrong because a 6-2 score would suggest a 400 point difference. If you use the +/- 400 formula, you have the same problem although it is a more accurate estimate for a match...
