FRER super faint examples?

Livi 🦊

If you got a TRUE positive - like it was proven later on - on a FRER but it was super faint.... could you post your test? I keep seeing lines on mine and everyone else’s FRERS and I’m starting to think they’re bad for evaps? I just don’t know how faint it could actually show because the “faint” ones that I see that are proven to be positive are usually BFP’s and not actually squinters.
