Sorry guys if this has been covered but it appears (I have given some of the recent comments about releases in this thread a fairly cursory glance) as if there is an assumption that an elbow plane requires more #3 accumulator.

The #3 accumulator is the angle formed by the left arm and club shaft, to quote: "Power Accumulator IS is formed by the angle established between the Clubshaft and the Left Forearm."

If the left wrist is level (that, if I'm not mistaken is an impact condition recommendation because it gives more support and control for impact) would this not create the same angle between the left wrist and forearm (assuming you are using the same club) and if so is there any requirement that wrist conditions should be changed due to plane angle. I can't seem to remember any place in the book where it says so or is contained therein through "obvious inference."

There is a wide spread misconception that to swing on a shallow plane, you must come into impact with non-level left wrist, like a left handed topspin backhand in tennis. As you said, the left wrist condition at impact is level, regardless of down swing plane.
