Drive Score

Score from 0-100 that evaluates driving quality based on events and histogram analysis.

Formula


Score = BASE + Σ(events × weight) + Σ(histogram × weight)

BASE: Initial score (typically 100)
events: GC counters normalized by distance (events/100km)
histogram: Percentages of time in different ranges
weight: Configurable multipliers

Classification

Range	Rating	Description
90-100	EXCELLENT	Excellent driving
75-89	GOOD	Good driving
60-74	FAIR	Acceptable driving
40-59	POOR	Poor driving
0-39	BAD	Very bad driving

Events are normalized to events/100km (according to DIVISOR). Negative values penalize, positive values reward.
