That applies virtually to every spec in the game and is not disputed.
Precise shots are buffed arcane shots that you can shoot while moving..
No mention of mainteining a 100% buff uptime of Steady Focus? No mention of target switching for killshot or mobs above 70% HP? No mention of manipulating arcane shot for Lethal Shots to shave off Rapid Fire CD? No mention of weaving in Lock and Load while having multiple available abilities ready? Even something basic like when to use Ais or Rapid Fire with Double Tab or setting up AOE optimally can be easy to not do right.

For the record, I'm referring to playing the game competitively; aiming for the highest parses while surviving and doing the mechanics properly. Then the nuances become more distinct, apparent and you'll find that movement around aimed shot is this one aspect to be aware of.
