Why are my XP points disappearing?

The XP points that we see on our profile, are points from the past 7 days. We reward being systematic on the ELLA platform.

For example:

1 January+100 points
2 January+50 points
3 January+200 points
4 January+100 points
5 January+50 points
6 January+200 points
7 January+100 points
8 January+50 points

If we logged in every day and filled out exercises every day then on the 7th of January we should have 900 points. But on January 8, we will have only 750 points because the points for January 1 will have disappeared. Only the last 7 days count!

Remember that for every day of inactivity, points are deducted.
