Well I am curious if thats how low it would actually register at that altitude. Zero and I are at ~3000 feet..... so I would be really curious to see what kind of readings you get.....

I am usually more concerned with a compression value that is >10% different from the rest....

IF they are all even then at least its natural wear and not some major scoring or burnt valve....

Let us know what you get.....
