Ejection pattern

I have become interested in the proper ejection pattern for various and properly/optimally operating semi-autos because people have said you can diagnose some problems just on ejection pattern alone. I was thinking of creating some kind of illustration or chart...something like the shooting error chart that everyone has seen.

What is normal for, say...a Glock, a Colt 1911, a Sig P226, Beretta 92, just to name a few . How about a Luger?

Where should your brass be landing when it hits the ground on that first bounce? At your 3, 4, or 5 o'clock?

And where will your brass land when your extractor and/or ejector is faulty or malfunctioning?

Sir;
Generally about 3 t0 5 feet from the port on a semi auto.

In 1911's with one piece extractors. Tune the extractor, ejector and select the proper recoil spring to put the spent brass in a nice pile at you four o'clock. The new ones with the extractor on the outside of the slide good luck!
