I hardly even notice Se, Ni, and Te PoLRs (I'm sure the Se is type-related). Fi, Fe, and Ne are probably the most painfully obvious. Although I'm getting better at recognizing it, I think Si PoLR in particular is kind of subtle; it mainly comes out in how a person moves and speaks, not in anything they say or do specifically.
I guess I don't really "notice" Ti PoLRs because I'm constantly seeing Ti problems anyway.
