Figures - Figures below show peak patterns “seated” on a “smooth” pattern. Some peaks arise from prototype use. For using the deheaping program, no abrupt chances from one integer to the next other than heaps, spikes and random “fluctuation” should occur. Yes, people avoid 13 and have a tendency to avoid odd numbers not ending in 5. Correction for avoiding 9, 11 and 13 are provided. What matters is that fluctuation is “quite” consistent with a “smooth” pattern with peaks arising from prototype and spiker responses occuring.

These curves  involve prototype heaping.

The curve on the right may have spikes, e.g. protrusions related to limits. Example 3 in documentation you can download deals with spiking.
