VERY Crackpot theory,

Neural systems have a masking factor. This prevents a stuck input from tying
up the whole net. Like when you stare at something and it leaves a negative
image in your eye. The negative image is the mask generated by the neural
system.

That may apply to time related items also, like when you are in a noisy room
and your ears adapt by "tuning" out the noise so you can hear better.

It may be that drummers instinctively play around the outside of the neural
"mask" time. If they hit perfectly on the beat every time, they eventually
couldn't hear themselves.
