A tight group can still miss the target
Grouping describes how close your darts land to one another. Accuracy describes how close they land to the target you intended. Three darts clustered in the 5 sector are a tight group if you aimed at 20, but they are not accurate. Separate those two observations before changing your throw. “All three went left” is more useful than “that visit was terrible”.
The drills below are observation exercises, not a diagnosis of your technique. A scattered group alone cannot tell you whether grip, stance, release or aim caused it. Start with a stable board and a clearly marked throwing line. The home dartboard setup guide covers those basics so your practice conditions stay consistent.
Make your starting position repeatable
Choose a comfortable stance that lets you stay balanced through all three darts. Notice where your leading foot sits relative to the line and how you hold the spare darts. Return to that position at the next visit. There is no need to copy a professional player’s exact foot angle or grip: the first task is to recognise your own setup.
Throw a few relaxed warm-up visits before recording results. Keep the same target for the whole visit and use your usual pace. If you are constantly stepping sideways or changing your grip after a single miss, the next dart is no longer a fair comparison. Save deliberate experiments for a separate block.
Drill 1: ten visits to one broad target
Aim at the broad single-20 area for ten visits. After each visit, record how many darts landed in the 20 sector and the main direction of any misses. Count a double or treble 20 as a hit for this sector drill, but note that it was above or below your intended single area. The hit count measures sector accuracy; your notes describe the grouping.
Look at the ten visits together. One dart in 1 does not establish a pattern. If most groups sit left of your intended point, you have a useful observation to investigate in a later block. If the darts spread in all directions, concentrate on repeating the preparation rather than chasing the last landing point.
Drill 2: group, then change target
Throw one full visit at 20, the next at 19 and the next at 18. Repeat that cycle three times. Use the broad single areas and keep all three darts aimed at the same point within each visit. This asks you to find a new target between visits while keeping the throw itself familiar. Do not compare the raw points from 18 with those from 20; compare target hits out of nine darts for each number.
Drill 3: change one thing and retest
If you want to try a small stance adjustment, first record five visits with your usual stance. Then record five with the change, using the same target and pace. Return to the original stance for a final five visits. This is a small experiment, not proof that one technique is superior. Repeat on another day before adopting a change because of a few good darts.
Keep these observations in a notebook: the scorer records points, not the physical position of each dart. Once you can repeat the broad-target drill, add Around the Clock practice or use the four-week practice plan. A useful next challenge changes the task without changing every part of your routine at once.
