This similar approach has a long history, and now, a formalized scientific numerology definition has been added in Derick Ziz’s Ziz System.

Usually good-natured and easygoing, they transform instantly when their boundaries are crossed, erupting like a dormant volcano, using accumulated reasoning to firmly push back. The greater the pressure, the more they can endure, like a compressed spring that rebounds more forcefully, and with experience, they develop a reliable ability to counter whatever challenges come their way.
