Nitro efficiency index (Asphalt 8)


 * Nitro type definitions
 * Level 1 = Triggered by firing nitro once. Basic level of nitro, and the longest-lasting.
 * Level 2 = Triggered by firing nitro twice, outside of the red zone . Equivalent to Perfect Nitro in terms of nitro efficiency.
 * Level 3 = Triggered by firing nitro again after triggering Level 2 nitro. Highest power, but the nitro gauge drains the fastest with this nitro level.
 * Perfect Nitro = Equivalent to Level 2 nitro in terms of nitro efficiency, except it has Level 3 power nitro. Triggered by firing the nitro once it hits the red zone (must be timed right).
 * Infected = More powerful than Perfect Nitro/Level 3 nitro, but will never run out until the player has been wrecked by Infection Overload . Available only in Infected mode.

Nitro efficiency is defined as how much of a full single Nitro tank (As a percentage) is consumed per second. For example, a Nitro efficiency of 12 means that 12% of a full tank is drained per second, and that it would take roughly 8 (100/12) seconds to empty a full tank.

Hence, numbers closer to zero denote longer-lasting nitro.
