That is good.
That's only half the story. Leakdown test would offer more complete story.

So would opening up the motor for a look see. For a visual of the pistons, rings and cylinder walls. To provide a more complete story as to the internal health of the motor that is.
If compression is good, if the motor starts, idles and runs normally, what is the point in doing a leak down test?
If you as an owner have a motor that starts, idles and runs well, and which has good compression, but seems somewhat deficient when it comes to a leak down test, and no moojoo juice will fix it, are you going to be opening the motor up for some sort of a repair?
Rhetorical question. No answer needed.
if it fails the leak down then you'll have to open it up. If it doesn't fail why would you open it up.
Leak down test will tell you more then just a compression test and may predict future issue that aren't being seen today sense most don't perform compression tests correctly.
Not going to get into a peeing contest over compression verse leak-down test. One will give you more facts about the actual condition then the other. Those are the facts.

Shlong as they're within the mfrs range and they're all within the same number you're good. Those numbers sound great.
