Stock motor compression

Does anyone know what the psi should be when taken a compression test?
Don't see it in my manual.
Thanks

Stock motor compression

http://www.smokemup.com/auto_math/pressure_ratio.php

basically, 13.1 lbs per ratio point with the barometric pressure of 29.92. 12.8 lbs per ratio point at a barometric pressure of 28.92

Not sure if you trust it, but looked convincing to me......
