Precisely, accurately (7)
I believe the answer is:
exactly
This clue is a double definition.
'precisely' is the first definition.
(I know that precisely can be written as exactly)
'accurately' is the second definition.

(Other definitions for exactly that I've seen before include "Indeed; verbatim" , "Precisely thus" , "Dead" , "how one might express agreement?" , "On the button" .)
