Agree with John.
Did you perform the test with the engine throttle plates open?
You can also put a squirt or two of oil down each spark plug holes- if the compression goes up, the wear is in the ring/cylinder wall; if no change, a simple valve job might improve your numbers.
That said, as discussed, how it runs is a bigger piece of the puzzle.
