Not necessarily. The default could happen 49% of the time, and everything else happens way less than 1%, but is weird.

So 51% of the time it’s weird, but not the same weird.

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".
