What are the compression figures meant to be on a fd 7 series rx7 with a mild port?

I'm using a cheap compression tester that isn't very accurate but gives a rough idea.
I'm getting compression on both lowers of about 84-88 it varies. And about 75ish on the top.

 

The port has nothing to do with the compression. If you have no miles on the build so far, drive it and let the apex seals get broke in than check and worry
