Scott, Great post... you discovered something very useful, though some may have missed a great tree for the forest (you presented a good sized forest

)
When I was Ohio State I discovered some techniques for improved learning/memorizing, which included the importance of time between study sessions.

That's correct, but it's not the sleep that does it, it's the time. Think of it as a "sinking in" requirement. This becomes very helpful when memorizing lyrics. For example, 3 10 minute study sessions with each session separated by 24 hours will produce much better results (retention) than one 30 munute session.
Another example... suppose you want to memorize 3 new songs. You might spend 30 minutes one day working on song #1, 30 minutes the following day on song #2, and 30 minutes the next day on song #3. Another method would be to spend 10 minutes each day on each song. Although the total time spent would be the same, you'll get much better results using the second method.
I'm old enough to have memory difficulties, but when I utilize this technique, it works for me.
