Points in Leaderboard

When I look up my progress, the points in the Point Summary do not match the Points in the Leaderboard.  Today, my points in the Points summary say 851 / 400. But when I look at the list of people on the leaderboard, it shows me as having 20 points. 

Also, if I check my points and then do a lesson and check my points again, it shows the same points as it did on my first look, even though I might have added another 100 points or more. The only was I can get the correct number is to quit CHROME and then restart it and check again. 

This happens as well!

It takes a minute sometimes for your recent points to show up on the leaderboard.

As for why your points for the day don't match… it looks like there are two “daily” points counters. One that resets (at midnight, I would guess) and one that counts everything for the last 24 hours. Your points for today (the star at the top and your daily goal) will be lower than your 24 hour points if you did anything the day before.

There's also the weekly, monthly, yearly and all time counters as well!
