However, most of the reported PGA geometries (e.g. slots, holes) have been determined based on the engineering intuition (i.e. trial and error) rather than in-depth phenomenological analysis.
Based on intuition, engineering judgments or previous tests, it is difficult to accurately estimate this coefficient.
