BAMILLER = the differences generally come from all the different test barrels, test conditions at that time, seating debths, bullets shapes and profiles.The list goes on. Basically no two companies use the exact same components or prcedures as the other. Not Every barrel or test jig is the same so a load that is max in one barrel may be good for another grain of powder in another. That is why most people do have several load manuals from whatever bullets or powder they use, so as to get a resonable "average" of min-max.
It is best to try and use the data that was tested using the very bullet that you are using so it has that bullets length figured in for oal. And why it is important to always start low and work up, watching for pressure signs.
