Modern Front-End Development for Rails: _schedule_day partial inconsistency B6 PDF pages (84, 140)

In Chapter 4 (CSS, PDF 84), the schedule day loop is refactored out into a partial _schedule_day.html.erb, but in Chapter 8 (Talking to the Server, PDF 140), the partial is gone and everything is back in show.html.erb. Since the book assumes a certain level of Rails knowledge coming into it, I would recommend having the partial already refactored out in the initial state of the app in Chapter 1. Irrespective, once it has been refactored out, the subsequent code examples should keep it in the partial.
