Experiment 1: Is there some pattern?

Although this is not continuous data, connecting with lines shows the values oscillate

Is there some pattern to this? Well, if we connect these lines - these points by lines - we can see that it's alternating. We have a high value; it is followed by a low value, followed by the value we expect, followed by a high value, followed by a low value, a value we sort of expect, high, low.  We see that basically, these are compensating for each other. So, yes, they are about 20 milliseconds apart, but if some get delayed, that means it decreases the delay until the next one, while it increases the delay from the previous one. And of course, since they continue to come along at 20 milliseconds, that means that somehow they have to average out to be as we expected 20 milliseconds.
