Question IP Too High, so what? and why?

[Centrals]

To be honest, I'm not sure exactly what people on this thread are referring to with regards to seat wear causing an increase in IP. Personally, after working on regulators for about 20 years, I have rarely seen IP simply rise as the seat wears. What I experience is that IP starts to creep a little, becoming less stable as the seat wears. As the seal between seat and orifice (or piston) degrades. IP does go up, but in my experience it's usually more like a mushy lock up with some creep, and then finally settling at a slightly higher number, but not consistently. Maybe other people have different experiences.

Totally agreed.
It is a slow process and eventually the 2nd stage starts to free flow gently. Learnt my lesson and always check the IP before blaming the 2nd stage.
