I would be thinking the same thing as you if I hadn't had an ultra-sound in November 2005, 5 flushes ago which concluded that my gallbladder was full of biliary sludge.
Impaired gallbladder contractility leading to bile stasis and sludge develops in association with a number of conditions including spinal cord injury, diabetes mellitus, obesity, and long-term treatment with some drugs.
I am convinced due to physiological changes that the vast majority of materiel expelled up to the 16th flush was from the liver. From the 16th flush onward my gallbladder started to contract and gain strength and that the 20th flush may be the zenith. As the capacity of the gall is 150 mL I would expect, approximately, this volume to be expelled before I am clear and the stasis is reversed.
I shall continue to flush until I am clear.
Best regards and many thanks for the time and effort you give to curezone.
