Metrics to define the cycle number from which the five variables characterizing the preconditioning response reach a steady and repeatable state obtained by the CCP and RCP protocols. Mean and standard deviation (M±SD) (p<0.001 for all variables) of the cycle number N* corresponding to the intersection between the 95% confidence band and the plateau line. Uncertainty of the repeatable response is measured by the percent error per number of cycles eN* where the variables were considered preconditioned.
