Hi, read my article. It describes the basis of mnemonics for long-term, not sports memorisation (Simonides/Cicero/Loki are the same).
Connections are erased I’ll assume because:
- Poorly distinguishable cube corners, worth checking.
- No consolidation in the form of representation to automaticity (4-7 days)
- If something is forgotten in an hour, it means you need to strengthen the connection or create a new one. If it remains, then access to it is weakened. If you don’t remember it at all, you need to make a new one - it has disintegrated.
