Thanks!

So, according to a table I found at your links:

Compression Test Altitude Compensation Factors

Altitude Factor
500 0.987
1500 0.960
2500 0.933
3500 0.907
4500 0.880
5500 0.853
6500 0.826
7500 0.800
8500 0.773

If I live at around 6000 feet, if I understand correctly I would have a factor of 0.840, which would mean that my engine at sea level when hot would now have 47 lbs of compression.

What is the compression it is supossed to have at sea level? I want to find out how far I am from what my engine should have...

Thanks,
Victor
