(Rybka makes it a tie, though annotators have said that improving White's King for the endgame was dubious.) Hence his report is believable. Again counting 1/2 for any tie: 33 matches at 12 ply (71.7%) 32.5 matches at 13 ply (70.7%) 35 matches at 14 ply (76.1%) 33 matches at 15 ply (71.7%) Weighted Hamming metric: 28 x 15 + 5 + 1 + 12 + 7 + 14 + 12 + 8 + 7.5 + 1.5 + 14 = 502 / 690 = 72.8% On this file it is especially important to separate the matches with big positive deltas from those without. I take "+0.75" as the measure of "big", since this is the dividing point for "+/- = large advantage" in Fritz.

Note that in chess terms, all except 59...b5 and 63...Re3 (amid many wins) have an "only-move" label. Hence even though they caused an impressive match rate from Move 25 onward, these should be discounted! The impression I get from the other batch is "pretty random". Hence I do not find evidence of cheating here.
