I agree, there is no exact science in interpreting and applying bible prophecy. There are only "preferred" methods, as you described.
Due to the billions of humans currently occupying this planet along with trillions of fish, animals and insects, there are literally at any second of the normal day, quadrillions of events taking place. When viewed from a distance, it is a busy and confusing place, bustling with frantic, hectic, and constant activity.
Given these facts, it is possible to expand and contract the applications of biblical prophecies to fit a variety of interpretations, both academic, historical, archaeological and scientific.
Only access to resources and the power to theorize, speculate, research, investigate and conclude pose limits to the individual private scholar.
