She gets a bit faster as she goes, getting used to the mental motions, though she continues the habit of physical motions corresponding to the magical ones. As she gets a better grasp on the invisible force of will actually doing the work, her shaky attempts get more solid and faster. It's still effortful, of course, not to mention kind of - tedious? Repetition, repetition. It's almost like washing dishes, the motions so learned as to be automatic, innate.
There's three phases to this kind of work, to repetitive tasks, at least for her. First phase, still learning the routine, focusing on each individual step and feeling out the process, actively paying attention. Third phase, when you've gotten so used to it your hands move without conscious input and your mind can wander freely. Or at least listen to music or gossip without losing the thread. Second phase is the awkward one. When it's starting to feel learned and natural, when you're starting to get in a steady swing, but not enough to go totally on autopilot with it. Your mind wanders, and suddenly there's a moment of confusion - what was I doing again? Which step am I on? Did I make a mistake just now?
When she starts noticing signs of the second phase, she pauses and stretches again.
