Compression Numbers Good???

So I tested the compression of the warm motor today. Cylinders 1-6 came back as 122, 122, 121, 120, 125, 125. Right side (passenger side) of motor had a little higher numbers. I did not charge the battery in-between and I did the right side first so I am thinking that contributed to the higher numbers. Or maybe that cam is just a hair different. Anyway, all were within 12 points (10%) of each other so I think that is good.
Anyone got a different thinking on these numbers?
(BTW, I am not sure I got number 4 totally tight so that may be contributing to the 120 when everything else on that side was 125)
