Summary: Type /gfdd in the chat window to see your Go Fast Don't Die score and rank.

Go Fast Don't Die is a simple, lightweight addon that provides a scoring and ranking system for group (4-person) dungeon achievements. It is intended to give players and guilds motivation to team up and tackle some of ESO's harder content. Points are earned by completing Veteran, Hard Mode, No Death, Speed Run, Challenger, and Trifecta achievements for all base game and DLC group dungeons. Ranks are awarded by comparing the total points a player has earned to the maximum points available. Ranks are fairly dynamic as the maximum points available in game change each time ZOS adds new group dungeons.

Scoring System:

Base Game Dungeons:
Veteran Mode completion: 5
Hardmode: 15
Speed Run: 10
No Death: 15

DLC Dungeons:
Veteran Mode completion: 10
Hardmode: 30
Speedrun: 20
No Death: 30
Challenger: 20
Trifecta: 50

As of the release of the Ascending Tide DLC, there are 4600 maximum points available. Each DLC release that includes a pair of group dungeons increases the maximum points by 320 points.

Ranks range from Rank 0 to Rank 10 and are awarded for each 10% of the current maximum a player earns.

Rank 1: 460 points
Rank 2: 920 points
Rank 3: 1380 points
...
Rank 10: 4600 points

Note that it is possible to lose a rank after the launch of new group dungeons as the maximum will increase. For example, a player with 1890 points is currently Rank 4, as Rank 4 requires 1840 points. However, if ZOS were to release a new pair of DLC dungeons, Rank 4 would require 1968 points and the player would then be Rank 3.

Use:

Go Fast Don't Die is a completely passive addon. To check your current Go Fast Don't Die score, simply type /gfdd in the chat window and your score and rank will be displayed.

I also HIGHLY recommend downloading Pithka's Achievement Tracker from ESOUI/Minion as it is a phenomenal visual display of your group dungeon achievements earned.
