"Under performers" was an extremely bad choice of words on my part and a simple, insensitive version of the post I made earlier.
@andyhb your point is valid and a solid reminder that the "performance" of an outbreak is more about its impact on lives than meteorological breakdown.
This last outbreak was significant in both regards. Those were some of the strongest, long-track tornadoes we've seen in a long time. Many were violent. Even one with lesser significance straight up slapped the dominator off the road. The Plevna and Grinnell tornadoes were Monsters. People might say Plevna was another radar anomaly, but they would be wrong because we actually have significant evidence of it being firmly planted on the ground...and violently rotating.

Look at the lights on the horizon for scale. It was a giant cone wedge. The type you see in textbooks. Andyhb shared a tweet from a meteorologist with an eyewitness account describing it as having "EF5" motion and a deafening roar. We also have radar images from just before and during collision with Plevna showing it started occluding as it hit town. It was an incredibly lucky, close shave for a town that was decimated

That was the end of its
90 minute lifespan. This, plus all the other significant tornadoes we saw leads me to conclude it was a 9 or 10 on the Meteorological "BS Scale" I created. For what it's worth the April 14/15 outbreak was my 7/10, and that's only because it had the kinematics to be a super outbreak. My original post was also in regards to the several hatched risks and 10+STP days we've seen completely fail to initiate. I didn't mean to offend and there has been some really good discussion about this topic already. This has been a very weird year.
