Default Compression test numbers, am I ok?

Did a compression test on my car today and a little worried the rings maybe on their way out.

The car makes good power and doesn't smoke or burn any oil.

Cylinder 1- 150 psi dry
Cylinder 1- 180 psi wet

Cylinder 2- 150 psi dry
Cylinder 2- 180 psi wet

Cylinder 3- 160 psi dry
Cylinder 3- 175 psi wet

Cylinder 4- 150 psi dry
Cylinder 4- 170 psi wet

Cylinder 5- 160 psi dry
Cylinder 5- 180 psi wet

Should I be worried or am I ok? This would pretty much determine if I keep the car or not. I appreciate any help anyone can provide. I'm new to Volvos and learning as I go.

you didn't mention which engine you have, but for T5 turbos over 155 is considered ideal. Considering you are consistent across the cylinders and 155 is within your margin of error, I'd say you are in good shape.
