Thirty minutes must be the time I take to make an easier difficulty.
Other than that I don't think I once took so little time to step a song with an average length.
And when I begin to step a song, I usually work on random lengths, I usually stop to a part that poses me problem or when I'm just too lazy to sync the notes. Making file is so boring and slow, I'd be masochistic to get a daily and regular session of stepping, I just happen to be done with it when I can and when I'm not too mentally tired.
The final result is the only thing that motivates me to continue working.
