Compression test results?

[Fretzy]

Done a compression test to see how my engine is holding up and it came back as 160/165 psi across all four cylinders. First cylinder had low reading at first but on 2nd attempt it went up from 100 odd psi to 160 WITHOUT doing a wet test! followed by the same results on the other 3 cylinders hitting 160/165 Engine was warm. 2015 reg on 74k miles. (quite amusing to watch as he was holding it as tight as he could to seal as the adapter would not fit im guessing the tester not being screwed in caused the first low reading till he managed to seal it better???)
