The fact that larger, faster dust devils cover more area means that they are more likely to be recovered by fixed station surveys. We can quantify this bias $f$ by taking the ratio of track areas for a given dust devil to the largest area:   \begin{equation}  f = \dfrac{A(P_{\rm act}, \Gamma_{\rm act})}{A_{\rm max}} = \dfrac{\Gamma_{\rm act}}{\Gamma_{\rm max}} \sqrt{\dfrac{P_{\rm act} - P_{\rm min}}{P_{\rm max} - P_{\rm min}}} \dfrac{\upsilon}{\upsilon_{\rm max}} \dfrac{\tau}{\tau_{\rm max}}.  \end{equation}
