There is something about having the plug out and watching the oil drain to the bottom of the pan that seems right. But, I'm willing to learn from someone else's experience.

After extraction of the old oil, adding exactly one quart of new ATF (or high-detergent oil), then measuring what gets extracted should answer that question.

Check clarity of the "rinse" for sludge and contamination. The ATF "rinse" can be re-used to lubricate chainsaw bars or—like WD-40—to attack corroded hardware.
