And FWIW, the last time I went to him I had 3 SIs: one was for a totally BS 40-year-old dx (have you ever in your life been diagnosed with... ?), one was an SI because of the way the dx was coded, even though the condition has no aeromedical significance at all, and the third was for real (a complicated PVD).
I am sure that isn't anywhere close to the largest number anyone has had, though. Remember that diagnoses accumulate as far as the FAA is concerned and are, in many cases, almost if not totally impossible to overturn. If I went for a 3rd class now I would need 4.
