Ultra Tight players with 5-6% VIP

[Madjohnny]

I haven't been running poker tracker /AHUD for a long time (2-3 weeks) but it seems common at the $50NL table to see at least 1-2 people out of the 4-tables I'm playing on with an insanely low VIP.

5-6% is basically Any PP + AK, or maybe 66+ AK, AQ, KQ or something along those lines.

What I'm wondering is, would someone playing that tight even make a profit? it seems the blinds would eat away all their money if hold out for the best hands.

What you guys think, what is the lowest VIP that still be +EV play.

edit: This is full ring 10 players I'm talking about.
