No, I am not. I know exactly what DPR is: an analysis tool.
In actual play, which happens encounter by encounter, it is irrelevant. What happens during real play is damage, or no damage, not an average. Why? Combats don't last long enough to overcome the tyranny of small numbers. Each combat is its own instance.
Now, if you had combats lasting dozens of rounds, I'd be less likely to make the above point. We both understand variance, and you do a nice job of providing analysis and an explanation of what you find. Not in the least, see above.
For your edification, and others', I'll point out that just because "people started doing this in 3e" does not grant an activity inherent virtue.
And as before, I am glad Kryx (and some others) do crunch them because I find it interesting for its own sake.
