You know, I don't really like this sort of comment. Someone goes to great effort to empirically verify something, something that is against common wisdom, then someone gets to just float in with 20/20 hindsight and say "Well, yeah, duh."
If it was so "yeah, duh", where's comment your about how blindingly obvious it was that common wisdom was wrong that dates from before somebody demonstrated it with concrete data and large test runs?
All you'd have to do to improve your comment is remove the last "Stop the presses" snark.
