For instance, if the UV critical surface has the finite dimension n it is sufficient to perform only n measurements in order to uniquely identify Nature's RG trajectory. Once the n relevant couplings are measured, the requirement of asymptotic safety fixes all other couplings since the latter have to be adjusted in such a way that the RG trajectory lies within the UV critical surface. In this spirit the theory is highly predictive as infinitely many parameters are fixed by a finite number of measurements.
