I assume nothing but that is more plausible than “mean absolute error”, which doesn’t even make sense in this context.

Mean absolute error is a measure of errors in estimated versus actual values.

And just the sort of ambiguous term the people who put out the list for public consumption would use, an acronym for a measure of errors in estimated versus actual values that would be a familiar term to someone involved with statistics? Like someone in the HDOH Vital Statistics?

Something that would look like a name but is an acronym for Mean Obsolute Error? But I'll take your advice, I'll give it a miss. Asking questions after the 'science is all settled' gets me nothing but insults.
