As the lack of correlation between mobility $\\mu$ and $\\Delta_{5/2}$ has been well established in previous experiments, we define, analyze and discuss the utility of a different metric $\\rho_{5/2}$, the resistivity at $\\nu=5/2$, as a high temperature predictor of $\\Delta_{5/2}$. This high-field resistivity reflects the scattering rate of composite fermions.
