That's where the testing comes in. Start a quick race on barcelona reverse with the race mode as versus and have a nitro starter active. As soon as the race starts, get into level 2 nitro. (Not a perfect nitro as the level 1 nitro duration before it will spoil the result). While the nitro is being used, avoid everything to prevent the duration from being extended (drifting, havoc, pickups, knockdowns etc). As soon as the nitro runs out, take note of how much time has passed. Divide that time by 100 (a full single nitro bar) and you get the efficiency rate.
