Why has my XP unexpectedly changed on the leaderboard?

Some users might have noticed their XP has increased on the leaderboard without having completed any XP earning activity. 

This is because we've recently improved the accuracy of the XP Leaderboard, ensuring XP earned across any DataCamp product or feature now reflects on the leaderboard. 

This improvement provides an even better measurement of where you stand against your friends, colleagues and other DataCampers.
