That's what I gathered. The report had a set of different potential abnormalities , by intersecting them all the number gets kind of low. Here's a photo of the report if you're curious https://imgur.com/a/LtG2KVb

If normal is 86-96% “abnormal,” it would seem abnormal is normal and normal is abnormal. ;)

English certainly has a bad habit of conflating good/bad with common/uncommon.

...doesn't that mean that those ("abnormal" ones) are the normal ones and the "normal" ones are the abnormal ones?

Also interested... seems insanely high
