I trust the BMW engineers too tell me when is too much, and when is too little to protect the engine. Not sure what happens in the middle between the marks though, but I think the rate of loss is consistent, and the oil meter drop reflects the shape of the oil sump.

I always carry 2 quarts in the trunk...although you would only ever need one at a time, 2 just seems better.

I have 78K on my M3 and about 30 track days and I am adding one quart every 3K. It was only about 45-50K that I needed to start adding oil. Apparently, 1 quart every 800 miles is still within BMW spec!

To get a faster oil reading use the "Quick Measurement" method from page 204 in the owners manual or look in the "Under the Hood section".
I have attached the directions from the PDF E92 M3 manual.

Using this method you can force another oil level reading without turning off the engine. If stopped on a level surface the updated reading will happen in about 1 minute, faster than shutting down the engine, opening the hood, finding a towel, pulling a dipstick, cleaning the dip stick, and using the clean dip stick to check the level. I would shut off the engine if oil needed to be added or you will have a big mess.
You can add 1/4 quart oil (engine off) then restart and force a Quick Measurement with the vehicle on level ground in about 3 minutes with a warm engine.
