I started tracking a couple of things systematically.

The 1st is at work. I noticed that some of the medical staff at my hospital aren't using our software correctly, and as a result are leaving the door open for some major drug-related problems. I asked for access to patient data from our database, but I was declined. Since I didn't have access that way, I just started collecting instances of entry error manually. After I collected a good sample, I presented it to my boss, who promptly got me the data I requested. Now I have a new problem of sorting through thousands of errors accumulated throughout several years of hospital operation.

The 2nd is at home. I started recording my SRS reps (how many flashcards I study each day) and my % correct. Today was an "above average" day as far as % correct goes. I'm hoping to try some interventions to see if they will have any effect on my error rate and/or long-term memory, but the 1st step is to get a good baseline.
