Those numbers look fine, be worried if one or more of them drop very low. For example 190 200 120 205.

i generally go by the rule if the high and low are within 20 something... then ur fine... what u look for in a compression test is not so much the numbers themselves and the u do the similarity of them

It is more important that the numbers are consistent, rather than high.

The numbers need to be both consistent and high.

You numbers are fine, they show a compression ratio close to 10:1 and they are within 15% of each other. So the rings are OK.
