lol. Senior VP of Stool Inspection... Yeah, not something I guess to brag about, but funny nonetheless and helpful.
None of those pics resemble what I flushed. Nothing I flushed looked anything like a 'stone'. So, I'm not certain if there were many/any stones and the round floating balls could have just been green crap. However, what you say does make sense and is along the lines of what I was thinking. These could have been pre-stone blockages that had not calcified, eh?
