Practice β the drill your darts say you need. No camera: tap where each dart landed.
Why this drill β and whether it is working
Other drillsHow it picks, and why it is built this way
A cold test is thirty darts at the bull before any warm-up, tapped onto the board. A tap is good to a few
millimetres against a throw that scatters thirty, so it gives your side-to-side and up-and-down spread
separately, which a list of beds hit cannot. The test repeats weekly, and it alone decides which way your
group leans: how a practice session went says little about what was learned.
Each lean has three drills. The first holds the target still. The second moves it every dart, which
scores worse on the night and is retained better. The third is the cricket numbers that lean costs most.
A drill opens once you have thrown six sets of the one before and put 22 of your last 36 darts in its zone.
That order is a default. Pick any drill under Other drills and it stays your drill, cold tests aside,
until you go back to the recommended one.
The zone is sized to your arm: it starts where about two darts in three land in it, tightens when
you put 27 of 36 in it over three sets, and opens again at 18 or fewer. The numbers appear a set at a
time, not dart by dart, and every cue points at the board, not at your arm. The papers behind each of
those choices are in the method notes at the foot of the page.
Practice darts stay out of your match stats. With profile sync on (Aim Lab β Your darts on file) every
tapped dart is kept with the rest of your darts history.
