Oh, sure, a factor of 1-10x is noise.
But if you normally write comments that earn 1-5 points, and then one comment earns 300pts, there might be something to the way you wrote it. Or might not. It might just be that you wrote the rebuttal everyone wanted to the stupid comment in a very popular thread.
But you should try to figure that out, because if—after eliminating sources of error—you're still left with an anomalously-high score, then the cause was probably you.
More than just with highly-positive scores, though, I also tend to analyze the type of writing I put into comments that ended up with negative scores. More often than not, it seems that my own problem is that I didn't sprinkle in enough "hedging words" (like the 'more often than not' in this sentence) and then someone came along with a single counterexample and a downvote storm ensued. I wouldn't have figured out that people had that reaction if the points weren't there.
