Some interesting stats I found while occupying time at work:
-No round was EVER repeated until S4. The first round to ever be repeated was a challenge in which you had to incorporate a specific word into a song.
-The first round to be repeated twice was the ARTPOP round where you write a song inspired by an image/painting
-The ARTPOP challenge was repeated for a 3rd time before any other round was repeated for a second (ARTPOP her impact)
-Only three challenges have been used in 4 seasons: the ARTPOP challenge (4,5,6,7), the Self Portrait Challenge (5,7,8,9), and the Twitter challenge (5,6,8,10).
Percentages of original challenges per season
1: 100%
2: 100%
3: 100%
4: 77%
5: 72%
6: 67%
