Two load charts, same crane, I picked the wrong one every time

Last month in Jacksonville I ran a 130-ton Liebherr for a week straight and kept second-guessing my pick radius. The manufacturer's chart in the cab was fine, but the site engineer handed me a printout from the rental company that had slightly different numbers. I compared them side by side on day three and realized the rental sheet dropped the boom angle limits by 4 degrees to be "safe." That small change made my lifts look impossible when they were actually well within spec. Has anyone else had to deal with conflicting charts from the same machine?
