You're perfectly capable of figuring all that out by yourself.

Jeffy is correct to say that I should be capable of working that out by myself.
I don't believe that any golfer should try and get extra CH speed by actively straightening the right wrist in the late downswing because that will likely lead to through-impact (or post-impact) flipping. I believe that it is perfectly acceptable for a golfer to allow the right wrist to passively straighten after impact - if he uses a full-roll hand release action. However, I believe that any use of a full-roll hand release action must be delayed until P7.2 or P7.3, so that there is no possibility of flipping or rolling through impact. That means that a golfer must "hold" the impact alignments of the two wrists through the immediate impact zone (between P6.9-P7.2) to ensure a stable clubface where the path/face continues to face the target. If you read that KM article on DH release styles, he does not explain the biomechanics that underlie a DH-release action.
I believe that there are two types of DH-release action - i) one used by a golfer who uses a delayed full-roll hand release action and ii) one used by a golfer who uses a no-roll hand release action. A "hold" action through the immediate impact zone (between P6.9-P7.2) in example i) is biomechanically performed by driving-and-holding the FLW/intact LAFW towards the target while allowing the right wrist to passively straighten. The timing of right wrist straightening depends on right shoulder position and the likelihood of "running-out-of-right arm. A "hold" action in example ii) is performed by driving the FLW/bent right wrist through the immediate impact zone using the body's pivot motion acting through an intact impact triangle. If one keeps ("holds") the impact triangle intact, then one is "holding" the FLW/bent right wrist in its impact alignment all the way through the immediate impact zone to P7.2+. The right wrist should optimally remain bent until at least P7.2+. I provided many golfer-examples of a no-roll hand release action in my review paper on "hand release actions through the impact zone" and golfer-examples included Ben Hogan, Lee Trevino, Mike Bennett, Charlie Hoffmann, David Toms, Sean Foley and John Erickson.
Jeff.
