In every detail, perfectly (2,1,1)
I believe the answer is:
to a t
I believe this is a double definition.
'in every detail' is the first definition.
(I've seen this before)
'perfectly' is the second definition.
('to a T' or 'to a tee' can mean perfectly)
(Other definitions for to a t that I've seen before include "perfectly well" , "Exactly right" , "In every detail" .)
