I jack it up as high as I can get it in the back. Then drain the oil and remove the filter. I go the extra step and leave it there for a day or two. Then put it back together and lower it back down. Plug is on the front of the pan so you really should tilt towards the front to get it moving.
Good Luck!

The Service Manual just says to have the car level. I never bothered with tilting the car forward when I changed oil myself. If you think about it more C5s have their oil changed by some sort of a shop than by the owners and shops don't monkey around tilting the car forward. The little bit of extra oil you get out is not going to flush any of the debris that happens to be lying on that flat oil pan floor so all you do is spend extra time doing something that doesn't have to be done.

I would think any metal shavings is more heavy than oil and would settle at the bottom of the pan and drain out first ,

I don't know about that 4%... I always elevate the rear of mine 4.7365258745632156325% when I change my oil. Lol, I've never heard it in those terms before.
To answer the question; I usually raise the rear up a little to get a little more of the old oil out. You're never going to get all of it out of the pan unless you drop it so don't worry about it too much...

I understand that 3.6 degrees would equal 4% given level is 0% and 90 degrees is 100%, but again, where will we place the protractor to determine our reference point?
We do want to be precise don't we? The last thing we want is to be compared to a Jiffy Lube.

I prefer an elevated rear myself.
