the score for 3dmark2001 is calculated thus
game 1 low/high
game 2 low/high
game 3 low/high
game 4 = nature...
the nature score has a higher weighting percentage wise than the other 6 tests mainly because it stresses the VIDEO card more...per my understanding..
since the other tests have absolutely NO bearing on the 3dmarks obtained there is absolutely NO reason for people who have oc'd their cards solely for the purpose of ONE run to stress it further by running meaningless tests
not to mention its a waste of time.. who really will sit through that crud ?
hence you will find most of the top scores out there do not have any tests run after game 4...
