Independent muon-excess corroboration
The argument
Because Auger's independent muon measurements show ground-level signals well above model predictions, and because a combined analysis of nine air-shower experiments finds a muon excess growing with energy above 10 PeV, the hybrid fit's preference for larger hadronic ground signals matches what methodologically independent measurements already indicate, making it unlikely to be an artifact of the fitting procedure or of a single detector's systematics.

The inference goes through: methodologically independent measurements finding the same directional effect make a fitting artifact or single-detector systematic an unlikely explanation for the hybrid fit's preference for larger hadronic signals. The argument's weight now rests chiefly on Auger's directly measured ground-level muon excess, which is verified across three independent measurement lines; the nine-experiment combined muon analysis points the same way but is not yet assessed in depth. The corroboration bears on the direction of the hadronic-signal shift, not on the fitted Xmax shift, so it strengthens rather than establishes the full claim.
