ya i actually emailed burton also and he said that three days works the best, but also didn't give any facts and couldn't lead me to where it was further studied. That video is pretty helpful... i just wish he used clearer graphs and images.

By the way why was it closed down for so long. I remember it saying closed for critical maitence but what the hells different? And why is that giant section missing?... someone doesnt want this method to be studied.
