You were hitting everything in the first half. Then a long round spent dead, a slow half-time, a five-minute wait for a teammate to come back, and suddenly your crosshair is a step behind. Every flick lands just past the head.
That is not in your head. It is one of the oldest, most reliable findings in motor-learning research, and it shows up clearly in the data from players on Online Aim Trainer. The good news is that it also has one of the fastest fixes.
Your aim has a warm state, and it fades
We looked at 26,625 pairs of back-to-back attempts at the same drill by the same player, and asked one question: does the second attempt beat the first, and does it depend on how long you waited in between?
While you keep playing, every attempt beats the last. Once the gap passes about 30 minutes, the warm-up you built is gone and you start again from cold.

| Group | Value | Sample |
|---|---|---|
| Under 3 min | +0.9 | 8,571 pairs |
| 3–10 min | +1.2 | 5,200 pairs |
| 10–30 min | +1.6 | 3,074 pairs |
| 30 min – 2 h | −0.1 | 1,356 pairs |
| 2–12 h | −0.4 | 2,005 pairs |
| 12–48 h | −0.5 | 4,033 pairs |
| Over 2 days | −0.3 | 2,386 pairs |
Up to half an hour apart, the next attempt is reliably better: by about 1 to 1.6 points of skill score, or 3.5% to 6.5% of difficulty-weighted score. After 30 minutes the gain disappears and turns slightly negative. A long break does not just pause your warm-up. It undoes it.
Why it happens: "warm-up decrement"
Psychologists have a name for this: warm-up decrement, the drop in performance on a motor task after a rest. It has been studied since the 1940s, and the modern evidence is striking.
- In 36,168 scores from the 2017 PDC World Darts Championship, the first dart of each set of three was less accurate than the next two, even though the pause between sets is only seconds long.1
- In a 2025 experiment, people stopped and moved around for about 30 seconds between rounds of a precision hammering task. Their first strike after each break missed by 14.75 mm on average; the second missed by 9.53 mm. The authors call it "the perils of the first try": breaking off the task "decouples the internal and external frames of reference."2
- The drop is temporary. Work on how fast different kinds of practice effects fade separates warm-up from real learning: they run on time scales that "varied by an order of magnitude."3 You are not losing skill. You are losing calibration.
In plain terms: your brain keeps a constantly updated map between hand movement and crosshair movement. Stop using it and the map drifts. The first few shots after a break are the ones that re-tune it, and right now those shots are happening in a live round.
Any drill brings it back, and fast
The most useful finding in this research is what fixes the decrement. In 1971, two classic experiments showed that resting did not prevent it, but doing a short, related activity right before resuming did, even when that activity was not the task itself.4,5 In one, people who rested for ten minutes showed "large" warm-up decrement, while people who spent the end of the break on a different, left-handed movement task showed none.5
The same thing holds for skilled athletes. In 65 highly skilled tennis players, the post-rest drop "was also eliminated by practice swings," while simply resting longer did nothing.6 And a quick reactive drill beat a static one: practising an open, reactive skill gave better scores for "at least the first two post-rest trials."7
Our players show exactly this. We took the first time each player played a given drill in a session, and compared it with their own average on that drill.
A single run of any drill removes about two thirds of the cold penalty on the next one. Warm-up transfers between drills.
Show the numbers
| Group | Value | Sample |
|---|---|---|
| Played cold (first run of the session) | −5.1% | 3,416 runs |
| After 1 run of a different drill | −1.8% | 1,573 runs |
| After 2 other runs | −1.2% | 1,318 runs |
| After 3+ other runs | −0.5% | 3,944 runs |
Then the question that matters for a mid-match reset: is 30 seconds enough? Players can choose 30, 60 or 90-second runs. When a session opened with a 30-second run, the drill played next came in at +0.4% against the player's own average. That was no worse than after a 60-second opener (−2.4%). That comparison is small (251 sessions opened with a 30-second run), so treat it as "30 seconds is enough", not "30 seconds is better". It is the same pattern as the darts and hammering studies: most of the recovery happens in the first attempt or two.
When to actually do it
"Between rounds" needs a reality check. The windows inside a round are short, and you need them:
- CS2 competitive freeze time is 15 seconds.8 That is not enough time for a drill.
- Valorant's buy phase is about 30 seconds,9 and you need it to buy and to talk to your team.
The windows that work:
- When you die early. Valorant rounds run up to 100 seconds.9 If you are dead with a minute left and nothing to call, that is your reset window.
- Half-time and the switch between games. This is where the 30-minute fade bites hardest.
- Any break longer than a few minutes: a slow queue, a teammate who went AFK, a reconnect.
What it will not fix: tilt
Be honest with yourself about which problem you have. If your aim is cold, a drill fixes it. If you are tilted (frustrated, rushing, arguing with your team), it probably will not. In a validation study of 488 players, tilt was described as lasting "from seconds to hours, with an average duration of 30 min."12
Short routines do help under pressure. A meta-analysis of 112 effect sizes found pre-performance routines improve performance, including under pressure (g = 0.70).13 But a 2026 meta-analysis found these effects are "smaller and less robust" in open, reactive skills like FPS aiming.14 In a survey of 1,007 gamers, the only coping habit linked to less tilt was taking your mind off the game for a bit.15 Use the drill as a ritual alongside muting chat and a few slow breaths, not as a cure.
The 30-second reset
- Keep a tab with Online Aim Trainer open before you queue, set to your exact in-game sensitivity.
- When you are dead with time left, at half-time or between games, alt-tab and run one 30-second drill. Flick or Micro Adjust both work.
- Do not chase a score. You are re-tuning, not training. One run is enough.
- Switch fully back to the game before the next buy phase ends.
You will still miss the occasional shot. But the miss that recalibrates your hand will happen in a drill, not in the next round's opening duel.
