The problem is without an exact amount, we have no idea when it is a PPE-deprived mage could supposedly be immune.
Would this same logic apply to ISP-deprived psychics?
In the very least, the thing which allows either to sneak into Chi-Town (the actual use of spells/powers) I hope we can agree would set off detectors.
I think the issue is my understanding of mages was formed from the 1990 RMB and may not yet be updated to reflect yet another RUE retcon.

"Sense psychic and magic energy: Like a blood hound smelling a familiar scent, the psi-stalker can detect the presence of psychic energy, specifically fellow psionic (ISP) and magic and supernatural (both with high PPE)."
When ability 1 was defined for the Psi-Stalker in RMB p 105, it mostly said the same thing, but the end was different:
psychic energy; specifically fellows psionics (I.S.P.) and magic (P.P.E. specifically oriented toward magic, techno-wizardry, and wizardry devices)
The explanation of "high" PPE was not originally present, only that magic meant having PPE oriented toward magic. So even a LLW with 1 PPE would still count. RMB still left 0 PPE up for grabs I guess.
Wasn't utterly clear if it meant 'total PPE' or 'current PPE' either.
