It's an interesting idea to keep track of your alone and social time, and to have the opportunity to max each of them out to see what your limits are. I've always thought I was happiest with about an 80/20 mix of alone and social time which I guess by most people's standards would make me a fairly extreme introvert. But reading your thoughts made me wonder if that would really hold up to a test, or if I could really handle a long stretch of more than, say, 3 days alone.
