Default Safe, reliable HIGH oil pressures 2011 stg2 wrx?

Can anyone with mechanical know how comment on reasonable oil pressure values on a newer 2011 stg 2 wrx? The 10 psi/1k rpm does not seem to apply to my car. Using Rotella 5w-40 I get about 7 bar (100psi) at cold start. After 10 mins or so operating psi under throttle is about 6 bar (85psi) at 3 to 4 k rpm and idle settles to about 2 bar. Seems kinda high to me, but I really know nothing about this.

End game here is wondering if I should look at oil with a bit less viscosity to bring pressures down, or are my numbers just fine for our engines. I don't push my car hard, for what that's worth
