Crossword Genius

Determined, Blair acted recklessly (10)

Ross

I believe the answer is:

calibrated

'determined' is the definition.
(to calibrate is to set or determine)

'blair acted recklessly' is the wordplay.
'recklessly' indicates anagramming the letters.
'blair'+'acted'='blairacted'
'blairacted' is an anagram of 'CALIBRATED'.
