Is this oil pressure ok?

Alright fellas here we go! So I opted to buy a stewart warner mechanical guage and the results are better from what I can tell. So at my idle in gear I'm looking at exactly 20-22psi. When it's on the warmer side in traffic it might hit 18-19 but I only saw that once. How's that sound guys. Here is a picture of it at 170° idle

Not to happy I scratched my dash plate but that's the least of my worries when I'm trying to solve a more crucial concern. Also had to switch the guages due to the oil line hitting the steering column support
