I pushed Jeff to post this before he traveled this weekend in order to have this video available for the community to watch over the weekend before we have the Office Hour Tuesday.
Unfortunately, that means he’s offline for most of the weekend, so I don’t expect him to be able to respond to your questions until Monday. You can also join the Office Hour Tuesday to converse about this (hopefully we have the room and time to address all the questions). I’ll make sure that the most popular questions and conversations posted here are addressed at the Office Hour. So be sure to click the 
(like) button on the questions you want addressed.
