There might be an average behavior but averages don't show you much when you really think about it....they are just an equation. Baseline really does stagger considerably. We all deal with very similar things in episodes and I do believe this shades our personality in a certain way. We might share more common ground than we realize. But it's all very individual for the most part. When stable I'm pretty even keeled but I have other issues besides bipolar which make me emotional even while stable.
