Just an editing point, Josh should absolutely not edit in the "please like and subscribe" video snippet between a complicated question and an extended answer. (starting at the 7:56 point),.
I understand completely that Josh needs encourage folks to like and subscribe, but I had to go back a couple of times to listen to what the question was and then fast foreward to Cube's answer to follow the train of thought.
Poor placement of the "like and subscribe video, Josh.
