On slide 71 - there is a mention of an averageCake function and an avgCake function. I am assuming these were meant to reference the same function, but since the names are NOT the same - they are two different functions.
Thanks for noticing! I bet you’re right. This is a great thing for a support ticket (email@example.com) rather than a forum post. I will make the ticket today, but if you notice anything in the future please don’t hesitate to point it out to Support!
