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: 40.58 base × 84.8% weighting.

Partial inputs flag incomplete source metadata. Provisional weighting flags a time-travel assessment that remains uncertain; it receives no additional confidence penalty.
