Wim,

You don't know this for fact. Maybe many, maybe most, maybe some,
   but not everyone.

Hybrid tuner is a term that recently came up this month
   to indicate a person who uses an ETD and aural skills
   to tune.

Strictly aural refers to one who does not use an ETD at all.

Strictly ETD refers to one who does not use aural skills at all.

 That's my understanding.
