This thread is starting to read like a soap opera, not that I watch soap opera's.

While that is BMW spec, you can't use an absolute value comparison for compression tests, only thing you can do is compare between cylinders for variance.

Ocha. What exactly does a leakdown test entail. I watched him do it. He removed all coil packs and sparkplugs , he did every cylinder at top dead center and measures them with a pressure meter. The meter read 100% each cylinder

All engines have leakdown past the rings to an extent, sounds like the correct process though. The leakdown test measures the amount of air that leaves the cylinder. usually it's at least 5% with most gauge sets.

No, usually a compression test will show "bad" and then a leakdown is used to pinpoint. Since your compression is good it's likely you don't have any leaks.
