Detailed Description
A candidate repetition period and how strongly the window actually supports it.
Period alone is not a usable answer. Any window returns some lag at which its correlation happens to be highest, including a window with no repetition in it at all, so a bare period silently reports structure in noise. Strength is the normalized correlation at that lag and is what separates a quantity that genuinely repeats from one that merely has a best lag.
A meaning phrased as a tendency to do something every few seconds needs both numbers: the period is the few seconds, and the strength is the tendency.
