It's the safety aspect of some of the calls which concerns me most.
Primarily in the vicinity of the airfield.
'Downwind', with no reference to which runway or circuit direction.
'Base leg', as opposed to 'Right base 02' or whatever.
? - if unspecified doesn't
"Downwind" mean "for the active runway in the published circuit direction for that runway"
"Base" mean "for the active runway in the published circuit direction for that runway"
If I'm doing something non-standard I'll put in the runway or direction but otherwise why clutter up airtime?
