I haven't looked at the dyno's you guys are referring to, but on V-Dyno, I like to set the "smoothing" to "2" or sometimes even "1". If you see a V-dyno that looks smooth on 1 or 2 "smoothing, then THAT is super smooth. Anything will look smooth on 4 or 5.
I really haven't looked at the dyno's, I just want EVERYONE to note that. I went I first started, I thought all my pulls were smooth. Turns out... Smoothing was on 5. After I knocked it down to 3, I found some spots to improve on.
