Go find a 25 mph wind on 11 stimp greens IRL and see if the wind has no effect.
Imagine you're @ a bowling alley (assuming those are basically completely flat) you have a machine roll a golf ball perfectly straight. You roll a ball 3 times, once with no wind, once with fans along the right producing a 25 mph wind, and once again w/ fans on opposite side. Do you think it is going to hit the center pin all 3 times?
