Dimensionless entropies predicted for NDAF-powered jets. Curves show the dimensionless entropy ﹩\bar{\eta }﹩ versus the time-averaged isotropic-equivalent prompt luminosity 〈L_γ,iso〉. The color represents the initial black hole spin a_BH,0, while each curve is traced by varying ﹩{\dot{m}}_{{\rm{acc}}}=0.01﹩–1 with the other parameters fixed at the fiducial values of W.-H. Lei et al. (2013). The red point with error bars marks EP241113a (C.-Y. Dai et al. 2026).
