The official description of Prehistoric Farm gives exactly one piece of technique advice: release the dig meter in the green for a better find. That makes a timed release the most repeated skill in the game, and a skill you repeat hundreds of times is worth five minutes of deliberate practice.

The trainer needs JavaScript to sweep. The idea still holds without it: the dig meter fills, and you want to let go while the indicator is inside the green band rather than riding it to the end.
How to practise so it transfers
Reaction training has a well-worn shape, and most of the value comes from doing the boring version properly.
Warm up at an easy setting. Slow sweep, forgiving band, ten releases. You are establishing the feel of “release before it arrives”, because every timed input has a lag between deciding and acting.
Then make it uncomfortable. Move to quick sweep or the tight band until your hit rate drops to roughly six in ten. That failure rate is where the learning is; at nine in ten you are rehearsing, not improving.
Finish where you expect to play. Three rounds back at your comfortable setting before you close the tab. Ending on success is not sentiment — it leaves the correct timing as the most recent thing you practised.
Watch the offset, not just the result. The trainer tells you how far off the band’s centre you released. A consistent “too late by a similar amount” is a lag you can correct for; a scattered pattern means you are guessing rather than reacting.
Taking it back into the game
Your hit rate here is not your hit rate in Prehistoric Farm, but the habit of aiming for the centre of the band rather than its leading edge is directly portable. So is the discipline of not watching the whole sweep — fixing your eyes near the band and reacting when the marker enters it beats tracking it the whole way across.
Once you are in game, measure your real hit rate over ten digs and drop it into the dig throughput calculator. That turns a reaction skill into a number of fossils per session, which is the form in which it actually matters.

Questions
Frequently asked questions
Does this match the real dig meter?
No, and it does not claim to. Project Mirvy has not published the meter's speed or the width of its green band, so the trainer gives you sliders instead of pretending to know. The skill transfers; the exact numbers do not.
What settings should I use?
Start on steady with the standard band, get to around eight hits in ten, then make it harder. Training slightly above the difficulty you expect is the point.
Does it save my score?
No. Nothing here is stored or sent anywhere — reload the page and the scoreboard resets.
