As with all random, pseudo-random and statistical analysis of this nature.... What I've got here could very easily be offset by someone else testing the same thing and getting different results, but these are mine. It absolutely could be a local weirdness of some sort, and I can't prove that it isn't. We can't see under the hood, so it will never be possible to say for certain. I am almost certain that other players will see this and say "But I never had streaks or swings like that", and they most likely will not be lying.
Have you summitted these results as a bug report? IIRC, you can attach an image to bug reports.
It probably has a higher likelihood of being seen by Larian than, uh...buried 4 pages in a Panel from Hell II Synopsis Forum post. Lol we're a bit off topic.
