How Titan works
Titan combines the archive’s quality, audience and legacy base with the significance of time travel. It is an index, not a score out of 100, and is distinct from the FMV archive’s scoring model.
Titan = base × [0.20 + 0.80 × (time-travel score ÷ 10)²]
This film: 48.56 base × 71.2% weighting.
Partial inputs flag incomplete source metadata. Provisional weighting flags a time-travel assessment that remains uncertain; it receives no additional confidence penalty.
