100% accuracy (exactly) does not exist. Measurement doesn't work like that - there's error. If we're off by a nanometer, that's still error.
Personally, I'd consider +/- 0.01 inches of error that is just as likely to favour one team or the other to be worth implemeting over the undoubtedly larger and possibly biased error we currently tolerate.
So the question I pose to you is: what is the maximum error such a system would need to achieve? We may disagree on the answer, but if your answer is zero then your position is irrational.
