Hi, my name is Jay
The normal oil pressure below 1000 rpm with warm engine is only 6 psig. At 2000 it should be about 18 and at 4000 rpm it should about 24 psig. The rate the engine warms to operating temperature should take about 5 minutes and what you describe is okay as long as it does not overheat.
