We propose an alternative paradigm to the conjectured Miransky scaling potentially underlying the physics describing the transition from the conformally broken to the conformally restored phase when tuning certain parameters such as, for example, the number of flavors in gauge theories. According to the new paradigm the physical scale, and henceforth the massive spectrum of the theory jumps at the lower boundary of the conformal window. In particular we propose that a theory can suddenly jump from a Quantum Chromodynamics type spectrum, at the lower boundary of the conformal window, to a conformal one without particle interpretation. While the Miransky scaling supports a near-conformal dynamics of walking type the new jumping dynamics does not lead to near-conformal dynamics featuring walking properties. We will also discuss the impact of jumping dynamics on the construction of models of dynamical electroweak symmetry breaking.
