Except his gradings aren't "helpful", nor are they accurate.
13- has, by traditional convention, been associated with a V7 bouldering grade, and I don't think the above route has three V7's (and one harder problem, per his notations). I've often heard it mentioned that this route has continual V4 climbing, but I don't know from personal experience.
Badman is also given 5.14a (somewhat morpho, but what route isn't), and has perhaps 2 V7 boulder sections, and certainly isn't as sustained as the aforementioned route.
BTW, I've never heard of, or given, routes grades based on any notion of "onsite" difficulty. Grades generally tend to settle in after a familiarity with the route, along with consensus.
