Anyone know for sure when these thing must open?

I have heard 20 psi, 40 psi, etc...

I just tested mine, and 4 open at 50-55 psi. 2 open at 10 psi... No way 4 are malfunctioning and all opening at the exact same pressure I thought...

Googling shows that Bruce andersons 911 performance book mentions they should open at 45-55 psi on page 84. Yet most posts on here suggest they should be opening way earlier???

Peter Zimmerman in his book also mentions 45-55 psi. See post 7 http://forums.pelicanparts.com/porsche-911-technical-forum/650664-piston-oil-squirters-question.html

I mentioned before that my oil pressure climbs really quick then plateaus at 60 psi... The squirter opening at 55 psi would absolutely explain that...

Why are others stating they should open much earlier? Is there variation from model to model?
