"Crazy approach" about sums it up.
It's said above (correctly) that you can't extend outbound if going above 110kts. Again, crazy. Why doesn't the AIP just quote PANS-Ops on this one?
As to turning inside the FAF - simple answer, don't. Regardless of the time, if you have a DME, don't turn inside the FAF or you'll likely end up unstable. That's much less safe than going to 6DME, regardless of the time.
Good old Airways. They get it right most of the time anyway.
