I think the book might need another chapter. My normal editing process makes things shorter, but for this book I might end up doubling the page count. I think I'll try to finish editing the rest of the book before making the decision on adding another chapter.
The new chapter would be very data heavy and in a sense it might look like I'm padding things out, but there's educational value here and it's supportive of several of the main points I try to present in training.
