Leader board isn't correct today
Today the leader board is counting my weekly and monthly tokens incorrectly for some reason. It says i have 371 this week when i actually have 600+ tokens
The leaderboard has been updated to better reflect the coins you have earned this week (beginning on Sunday) and this month (beginning with the first of the month).
This allows you and your friends to compete on a level playing field by starting everyone off at the same place each week/month and gives a clearer idea of how many coins you need to earn in order to pass somebody.
Why do you believe it is not a "level playing field" to compare how much people studied during the past 7 or 30 days?
When a new user joins the site, they can be anywhere from 0 to 29 days (0 to 6 days for weekly) behind the curve, depending on when they joined. With the old system, they were guaranteed to need the maximum number of days (29 or 6) in order to be on par with everybody else - ie, have the same number of days of activity reflected on the leaderboard. With the new system, there is significantly less 'catching up' required in order for these new users to compete fairly. For any given day, a user now needs an average of ~15 days of activity in order to catch up as opposed to 30.
This actually extends beyond new users to any user that alters their pattern of activity, though to a smaller degree. The results of a change (either an increase or a decrease in daily activity) is evident more quickly on the leaderboard in the same way it is with a new user - instead of always needing the maximum number of days in order to be reflected on the leaderboard fully, the number of days are dependent on where in the rotation the new pattern began.
