Machinbird, how often does the computer perform that process you speak of. They are digital computers. That means they must sample the data and make what they can with it. That's why I looked at the concept of three things with six holes total plugging up with sufficient simultaneity that it would not be noticed.
If the individual inputs are smoothed from VERY noisy data that smoothing may make the simultaneity credible to me. Without that extreme smoothing process "all at once" really bothers me.
