Well, again, what you get depends on what's happening with the underlying. That doesn't mean analyzing all ten of the underlying. But it does explain why the seeming chaos of the open occurs and why it isn't the same every day. For that you'll have to provide context, i.e., the hourly chart. Once you've found the important levels and focus on those, the mystery dissolves.
As for "oomph", that depends on the volume. If you want real oomph, focus on hinges, what I called "ranges on steroids" in the appendix on hinges. They are a classic example of compression and expansion, IF the volume is right.
Can it all be quantified? Probably not. But it's awfully easy to see.
