Q:  3.15.18  6:22 pm what's your suggestion for a not time-consuming method for clearing the block?
A: my method is to walk over to the door, and touch the door handle. then return and play the song, at tempo, from the beginning, and pay very close attention to the moments right when you reach the known end. at that moment the solution is most likely to crystallize. quickly ascertain as many clues as you can from that moment. then after that, re-set and do it again
