Compression Testing Pressures

What compression should I have on cylinders ?I've done a test and I want to know if it is ok or not.The gauge readings are over 10 to 11 in all cylinders ?THX!

For an AAN the figures are:

Compression pressures
New: 9-14 bar (131-203 psi)
Wear limit: 7.5 bar (109 psi)
Max. permissible pressure difference between all cylinders: 3 bar (44 psi)

Check page 42 of 93 in thie AAN engine manual (like Section C in the Bentley) for similar but different figures:
