Every place I've been we measured such weirdness outside of the 95'th and 99'th percentile. Anything out of common occurrence beyond the 99'th could be weird or interesting or fascinating. I still wish I could share the incident of a single NIC on a single server taking down an entire data-center, that was both weird and fascinating.
If there is a "default" then "everything else" is not weird. The conclusion is "this thing doesn't work most of the time so it wouldn't be weird if it doesn't".
So 51% of the time it’s weird, but not the same weird.
