My jump shot really is hopeless

Will practice perfect my jump shot? Stanford researcher Mark Churchland thinks maybe not. 

New Scientist:

Contrary to conventional wisdom that movement variability is caused by muscle activity, Churchland’s team found that neural activity accounts for about half the variations [in experiments conducted with Macaque Monkeys]. In other words, training muscles to perform a certain way through practice, such as countless hours teeing off or shooting a basketball, will not produce the same shot every time because the brain's behaviour is inconsistent.
