>This must rule out (though there's reason to like some of these);
>Diving - yes they twist, etc. but how do you measure a perfect score
Start with perfect for stated dive according to rules, then deduct for
variations from 90 degrees at entry, throw out the highest and
lowest scores from the group of judges, average the rest, then
multiply by the Degree of Difficulty for the dive. You'll notice that
there's (normally) little difference in the individual scores, indicating
that what might be casually seen as variables are really constants.
Yes, biases do show up at times, but that's why the statistical correction
is made (plus, that will be that judge's last appearance at a meet).
Where does anything requiring personal equipment fall? There's an
inherent (in)accuracy in bows, rifles, badmitton racquets, boats, etc.
that has nothing to do with the athlete (but must meet requirements
stated in the rules for the sport) , but the sports qualify under your
given requirements.
Fencing would be out...
Gymnastics out? How long can you hold a cross on the rings?
What? No strength or agility here?
The horses I gotta agree with you on.
Time for another cuppa coffee.
