Those number look good, might want to decarb the motor and see if that brings them up alittle, but those are not bad. I take care of 3 V4 Evinrudes, they all have compression numbers between 120 and 125. Your gauge might read alittle low, but the main thing is that they are even ( within 10%). Anything over 100 will work fine.

not only ok, they are a-ok.

So many variables when testing, that as stated, it is the difference that counts. No worries there.
