esabogal,
Yes, that is AMAZING…thank you for posting that very illustrative graph.
Lesson to be learned is that getting an annual serum urate level at the doctor and showing “normal” is no guarantee that tomorrow or after tonight's dinner or over the coming weekend, one's uric acid is not going to be high enough to easily precipitate. The swings in uric acid are quite dramatic. That's why I often say that while 6.0 is usually deemed safe, a 4.5 is FAR safer and less likely to give you an 9.0 after tomorrow's delicious shrimp scampi.
(I hope your doctor has you on 300 mg. allopurinol, esobogal.)
