[V8] compresion testing

[quattro]

Need your help guys.. I planned on doing a wet/dry compresion test on my v8 this weekend to determan if it was worthwhile rebulding my heads( If rings are shot, i wont bother with the heads.) Now looking at the manual, it shows the wear limit at 109 psi and new being between 145-189 psi. well on cylinder 1 i scored a 205psi dry. what gives? did i mention that this motor has 204k on it? Further more, the manual states that the cylinders should be within 43psi of each other.......that contradicts the 10% from the highest number Iv heard thrown around. Is this a missprint? Does anyone have some good numbers for me? Thanks
