Decision signal
Use a mixed strategy: fewer packs plus targeted trades.
This is a session-level efficiency signal, not a guarantee. Pack opening can still have entertainment value.Interpretation
Efficiency, not a command
- Use several sessions
- Compare cost per new sticker
- Keep entertainment value in the decision
Why duplicates rise
As ownership grows, a random pull is increasingly likely to match a sticker already recorded.
Track several sessions
Separate new album additions from duplicates using the same method each time.
Compare alternatives
Compare observed cost per new sticker with local trades, missing-sticker services and postage.
