Delta Force: Black Hawk Down
Fast aim against dense hostile crowds is the core test
World Tour Soccer 2002
player control, passing and shooting precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Large multiplayer servers add human positioning play
World Tour Soccer 2002
opponent play in human matches adds reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Delta Force: Black Hawk Down
Spawning enemy placements vary slightly between attempts
World Tour Soccer 2002
minor bounce/ref randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
