I think sleeping might help you work on the assembly program because its state and structure is made easier to recall and understand after you've slept on it. But my opinion was more based on solving math problems and learning musical pieces and athletic skills than understanding hare-brained programs.

On the other hand we might ask, is three 8 hour days better than six 4 hour days? What if there are break days in between the 8 hour days? Maybe only the first night of sleep on a new program is particularly effective. Who knows.
