Our Methodology
Our prediction engine uses a 3-layer weighted model trained on real wait time data collected every 5 minutes from all Tokyo Disney Resort theme parks.
Layer 1 — Day-of-Week Averages: Recency-weighted averages from the same day of week over the past 60 days. Recent data is weighted more heavily using exponential decay.
Layer 2 — Momentum: A 7-day vs 30-day trailing trend multiplier that detects whether crowds are rising or falling.
Layer 3 — Seasonal Calendar: Overlays for Spring Break, summer, holidays, and special events that historically affect crowd levels.
Accuracy is measured as the percentage of individual ride predictions that fall within 10 minutes of the actual posted wait time, calculated at end of day.
