 What about somebody wants to know, is 15 hours acceptable? Does it have to be 16? Yeah, 15 hours is acceptable. The way I set people up in my program is I kind of actually tell them more of a 17-7 method, more than a 16-8, because if you default back an hour from the 17-7, then you're still in the 16-8, if that makes sense to your listeners.
