Ballpark level (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tier
'ballpark level' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tier that I've seen before include "Row, layer" , "Level within hierarchy" , "Row in theatre" , "'Level, grade (4)'" , "range" .)
