Quick answer
Upgrade the pickaxe when your current layer starts draining time. Lucky Pickaxe and Six Seven Pickaxe are verified game-pass names, but their exact performance still needs direct gameplay proof.
Upgrade rule
If your run spends more time waiting on blocks than collecting and selling, your pickaxe path is probably behind your depth target.
Verified names, not stats
The public game-pass API verifies Lucky Pickaxe and Six Seven Pickaxe as pass names. It does not verify exact mining power, luck, or value.
What to record next
The next useful proof is a screenshot or clip showing the pickaxe menu, current cost, visible bonus text, and the layer where it becomes worth buying.
