When a collection outgrows the spreadsheet
Organize the collection. Not your life.
A spreadsheet works fine for a dozen pairs. Somewhere past that, it starts working against you.
A spreadsheet works fine for a dozen pairs. Somewhere past that, it starts working against you: rows go stale the day you add a new pair, a value typed in six months ago never gets revisited, and nobody can say with a straight face which cell is still accurate. The collection didn't get out of hand — the method just stopped scaling.
The fix isn't more discipline, it's a system that doesn't need constant upkeep to stay honest. In CYKI, a pair is catalogued once — its exact release, your cost, your size — and its value keeps itself current from there, because the app is pulling live market data rather than waiting for you to look something up and retype it.
This isn't about reorganizing everything you own. It's about the one part of it that actually has a market attached, kept in one place instead of scattered across notes, screenshots, and a sheet that's three months out of date.
There's no fixed pair count where this kicks in — for some collectors it's thirty pairs, for others ninety. The spreadsheet isn't wrong for stopping there; it was never built to keep pricing itself past a certain size.
