The OMG Ratio

Years ago there was a tournament that offered a special prize for the "Most Efficient Use of Energy" (IIRC). This was calculated as the total number of moves played by a player in the tournament divided by the number of wins. The smaller the number the better. I believe the event was sponsored by a power company.
In the same vein is what I would call the OMG ratio. This is the number you get when you divide a players rating by the number of moves played in a game. In this case the bigger the number the bigger the OMG factor if said player loses the game. Excluding results due to mobile phone defaults, or simply not showing up (although in the case of Fischer this is still pretty big on the OMG scale), once you reach a ratio of 200+ you know something pretty spectacular has happened.
Here is an example from the 2001 FIDE World Championship KO. Motylev and Shirov play a messy QGA, when on move 12 Motylev finds a spectacular losing move.

Shirov,Alexei (2706) - Motylev,Alexander (2641) [D20]
FIDE-Wch k.o. Moscow (3.3), 02.12.2001

1.d4 d5 2.c4 dxc4 3.e4 c5 4.d5 Nf6 5.Nc3 b5 6.Bf4 Ba6 7.Nf3 b4 8.Bxb8 bxc3 9.Qa4+ Qd7 10.Qxa6 cxb2 11.Rb1 Rxb8 12.Ne5 Qb7 13.Rxb2 1-0

It can happen to anyone who plays Chess, but a blunder by a player of this level gives us all reason to hope and not to be so hard on ourselves after our inevitable blunders...
