What do these compression #'s mean?

My car has been burning oil for a while, I'm tired of it so I decided to test the rings to see if I could get away with a freshening of the head. I only see it smoke when it has been idling for a few minutes (3-5).

I need some advice on if the rings are okay. Here's the #'s

cyl1 195 wet>235 (used capful of oil)
cyl2 200 wet>230
cyl3 200 wet>230
cyl4 200 wet>235

All vacuum readings indicate a healthy motor. Please tell me what you think I should do. I'm tired of putting in oil. Nt compression is supposed to be 192psi and the service limit is 145psi. I didn't know if I even needed a wet test, but did it anyhow.
 
Thanks, just wasnt sure since it had higher comp than its supposed to have. lots of miles 176k.

Most likely the problems are the valve seals.

Or, it could be the rings. Perform a leakdown test as recommended to get a grasp on where the oil consumption is coming from.

Let us know what you find,

Andy
