• Requirements are based on the scores of all users on a list and will change over time.
• Your score on the list will automatically be adjusted when the star requirements change.
• Requirements for lists with 10 or more users:
  • 1 star: 1 item
  • 2 stars: top 80% of users
  • 3 stars: top 60% of users
  • 4 stars: top 40% of users
  • 5 stars: top 20% of users
• Requirements for lists with fewer than 10 users (not enough data to use other method):
  • 1 star: 1 item
  • 2 stars: 15% of items
  • 3 stars: 30% of items
  • 4 stars: 45% of items
  • 5 stars: 60% of items

We changed the scoring system to account for the wide range of difficulties of lists.

• The new system awards stars based on your score relative to other users.
• Your star score on a list may change slightly over time as the average score for that list changes.
• Total star counts are updated at least daily.

LC score is an index measuring all of a user's activity on List Challenges. To calculate it, the following values are added up:

• Stars Earned x 0.1
• Items Checked x 0.01
• Lists Used x 0.1
• Votes x 0.01
• Published Lists Total Users x 0.001

Notice that you don't get credit just for publishing lists - people have to use your lists (the more the better). So instead of making lots of mediocre lists, make really good lists that people will find interesting and then promote them on social media.

• Where is it? - Click 'more stats' at the top of a list page.
• What is it? - The graph shows the number of users that got each score.
• What are the star areas? - Each star area represents 20% of users, and the minimum scores required to earn another star on the list.
