The useful figure is the balance of the pressures, if say the engine is for example 7,7,5 then although 2 of the faces on that rotor are good there is an issue on one of the seals.
I usually go with something like this:
8s = new engine after bedding in
7s = good, strong engine
6s = engine is ok, its used but still fine
5s = best start thinking about a rebuild
If you look after the engine then it should last ages, its usually the old fueling or cooling system that damages the engine rather than anything internally wrong - overheat it or run lean on boost it usually causes expensive issues.
