Here is the thing, the Dervy stat weights say that Sksp is actually rated a little higher than Det is right now, since Det has had severe diminishing returns over the course of a season. I don't know how seriously one should take those stat weights but the same weights by the same guy do affect the BiS for other jobs and they get it right from what I can tell.

If that was the case, then wouldn't this be better?
