Normalized probability density functions of Pf values for EFN meteoroids on JFC-like orbits, segmented into those with more than 50% and less than 50% of clones reaching q > 2.5 au. The bold vertical lines at Pf values of 0.85, 0.27, 0.085, and 0.027 are the limits for the Pf classes. The probabilities sum to 1.0 for each Pf value, emphasizing the comparative likelihood of belonging to either distribution (seen in Fig. 21a) and providing a probabilistic framework for understanding meteoroid origins in the context of strengths. While the distributions are significantly different, their overlap does not make Pf values a good discriminating mechanism between the stable and unstable comet-like meteoroids in the dataset.
