Regular-season strength
Strong seasons matter because franchise quality is not only about the years that ended with a parade.
How FLI Works
No mystery math. No secret vibes coefficient. Just a clearer way to read franchise history across eras. This is where Frozen Ledger shows its work: what the score is trying to measure, how lineage is handled, and how to read the main outputs.
What FLI measures
Frozen Ledger uses Frozen Ledger Index (FLI) to compare NHL franchise history across eras. It pulls together season strength, playoff results, championships, and long-range franchise continuity so the all-time picture is broader than one headline number.
Think of it as a structured way to ask two questions at once: how high did a franchise peak, and how much real historical weight did it build over time?
Scoring pillars
Playoff weight
Deep runs matter because postseason success changes how a season is remembered and how a franchise is judged.
Long-term staying power
A franchise that keeps showing up across eras builds a different historical case than one great burst and a long fade.
Why Cups matter, but are not everything
Stanley Cups are central to franchise legacy. Frozen Ledger does not water that down.
What it avoids is treating every non-championship season as basically the same. Great teams that fell short still matter. Repeated contention still matters. Context still matters.
Where the NHL History Guide helps
The road to a Cup has not looked the same across every era. Use the NHL History Guide when the real question is what that postseason structure meant in that version of the league.
How to read Total FLI, Average FLI, and Season FLI
Total FLI
The full cumulative weight of a franchise’s counted history. This is the all-time volume number.
Average FLI
The average FLI per counted season. This helps shorter and longer histories sit on the same table without pretending they are identical stories.
Season FLI
The score for one specific campaign. This is the best way to read peak seasons and standout years on team pages.
The Glossary is the fastest place to decode these labels if you just need the quick version.
How lineage works
Frozen Ledger follows franchise lineage when the franchise record itself continued. That means a team can carry earlier names or cities into one connected record after a relocation or identity change.
That is why the site separates a franchise’s current identity from its full lineage. A team page tells you what the current identity is. Frozen Ledger tells you how far the connected historical record goes.
Limits and interpretation
Frozen Ledger is meant to be transparent and useful, not mystical. It is a framework for interpreting franchise history, not a decree from hockey heaven.
Era context
Different eras created different competitive environments.
Playoff context
Different playoff formats changed what a run actually meant.
Schedule context
Different schedule lengths shaped what a dominant season looked like.
That is why the rankings, team pages, FAQ, Glossary, and NHL History Guide are designed to work together.
