Figure 17. A combined model with τR rate-limiting cannot account for the Murnick & Lamb data if R* lifetime gain dominates
Analogous to what was seen for the RecRK model (Figure 6), when τR is rate-limiting and the stronger of the two front-end gains modulates τR, the combined (R*-activation-RecRK) model cannot account for the Murnick & Lamb  data. It cannot generate large enough changes in Test flash Tsat, and the model Tsat versus delay (blue curve) never falls below the slope of -1. This rules out such a model. Thus, if both R* activation and R* lifetime gains are present, the R* lifetime gain cannot dominate.
