Had asked some friends to look at this thread. 613 was my number in a 17 week study on stress conducted by the University of California, San Francisco Health Sciences Campus in late 1992-1993. I had researcher/interviewer Myra Young. I showed her many of these documents dated up until then. Or sent them copies after I left the study in mid-March of 1993.
