The fastest times run in the Guineas since 1994 have been by Mister Baileys 135.08 on GF in 1994. Pennekamp 135.06 on gf in '95 and Cockney Rebel 135.28 on Gf in 2004. RP ratings respectively of 122,127 and 124. Kings Best who ran 137.77 on gd in 2000 got an Rpr of 131. There seems to be quite a variance in the ratings for horses running similar times.
George Washington got a rating of 127 for running 136.86 on Gf in 2004 , he won by 2.5 lenghts.In Kings Best case he won by 3.5 lenghts which seems to be the only reason for justifying his rating of 131. George Washington got a rating of 127 for running 136.86 on Gf in 2004.As far as I can see the winning distance seems to be the main criteria for giving a higher rating than average, apart from that the criteria for giving the ratings seem to be garbled. Any thoughts on this would be welcome.
