Scaling 1 has better accuracy than Scaling 2. However, Scaling 1 overestimated the $f_{\text{BS}}$
value for reversed shear equilibrium. Although Scaling 2 does not have internal current profile term, it can predict the $f_{\text{BS}}$ values to a certain extent for the high-$f_{\text{BS}}$ equilibria which are expected for next fusion devices.
