Just random happenstance. Don't worry about it.

I would say don't worry about that too much either. You don't show any C2 errors, so that isn't an issue at all. And your C1 error rates, while not as low as they can go, still aren't terribly bad. If you want to do better, your best bet at this point is to try new media. CMC isn't the best of quality, although people do get serviceable results from it. Taiyo Yuden (e.g. Fuji in North America) is always tops in LiteOn burners, and I have had good success with the 48x Verbatim DataLife Plus (SuperAZO) discs on my LTR-48246S and even 40x and 48x TDK and Maxell branded Ritek discs.
By the way, every session of a multisession disc eats up around 14 MBytes of space in overhead, with the first session using up almost twice that. So, if you have a choice, it is better to group a bunch of small files together rather than writing them one per session. There is nothing inherently wrong with writing a very small amount of data per session, it just isn't very efficient.
