Yes, agree with what KevinM said. BWM say the oil needs to be changed something like every 10K or once a year so the break-in service 'short cycle' is to get the initial fill oil out of the engine and diff which gets contaminated with tiny metal particles which have come off the gears and other rotating parts. You would hope the 1200 number comes from testing where BMW determined that was the optimum point to remove the initial fill oils.
