I think you missed my point... I didn't want to call it that. I notice 
that it is already called AVAR.

This is a good resolution. I would rather prefer "normal" being replaced 
with "original" or something as the context would select which is the 
"normal" one, which is a subjective matter.

The definition actually does not result in a particular algorithm (which 
popular beleif seems to imply), so one has to be carefull in putting 
judgement or preference in the prefix.

I think this particular issue is beaten pretty dead by now. I at least 
picked up a few important lessons. I hope others did too.
