Okay, so the practice area seems to be a little misleading. It shows you your progress on the individual sections, but it seems that if you achieve 100% on one verse, it will bump you to 100% on all verses, even if you didn't practice them all. I found this out via (I Can't Get No) Satisfaction. I've been practicing that first verse for the past couple days, and finally nailed it 100% today. It showed that all of the verse sections were now at 100%, so I assumed that meant all of the verses would be played the same. Except they're not. I went to play the full song and was completely thrown off when I got to the second verse. Not a huge deal, because I can still go back and practice those areas, but it would have been nice to know from the get-go.
