How scoring works

1 · Normalize both tracks

Your drawn path and the official track are each resampled to 100 evenly spaced points along their length. This makes a 4-waypoint sketch and a 40-point official track directly comparable, and means drawing more waypoints does not help or hurt you.

2 · Average track error

For each of the 100 sample pairs we compute the great-circle (haversine) distance in miles between your point and the official point. The mean of those 100 distances is your average track error - the primary ranking metric. Lower is better.

ATE = (1/100) * Σ haversine(predicted[i], official[i])

3 · Formation error

The distance between your first waypoint and the official origin point is recorded separately. It is reported on every entry and used as a secondary signal.

4 · Intensity tiebreaker

If two entries land within a hair of each other, the entry whose peak-intensity call is closest to the official peak category on the Saffir-Simpson scale ranks higher. If still tied, the earlier submission wins.

5 · Publication

Scoring runs only after an administrator publishes the official track. Every entry is scored in the same batch, ranks are written to the public leaderboard, and the top rank is marked the winner. Disqualified entries are excluded before ranking.
