Agree it's probably not an issue. But the behavior isn't uniform. Most of the time the accuracy indication doesn't fluctuate like this (though it may change if you switch targets and lose the accuracy gain from repeat shots and the like).
This is an outgrowth of attempting to understand in more detail how the accuracy stat affects chance to hit. LDO, higher is better, but I'm interested in being able to make informed tradeoffs between, for example, accuracy and kill, in which case it matters how much more likely to hit a higher accuracy weapon is. I'm using the indicated to hit % rather than having to run statistically significant tests (which would basically be prohibitive). But if the to hit indication fluctuates, I have to consider how reliable a metric it is.
[Yes, I may like to analyze things more than the average bear.
