Plucking as a defense against chokes is basically that you use your arms/hands to pull the attackers hands off your throat a small amount and pin them to your body - getting enough room to breathe again, and then proceeding to counter attack.
This makes sense to me as a possibility and fairly effective from the front.
However, in krav maga it also seems to be a defense taught when choked from the back where you reach your arms up and behind your head to pluck the arms, pinning them down at the wrist or thumb area.
This feels kind of awkward to me to reach up and behind my head to pluck the arms.
It feels like it isn't so effective as say, throwing an elbow to the solar plexus, or to the head, or stomping a foot, kicking the shin or knee, or stepping forward as you turn and raise your arm.
Do people here consider it a decent technique to pluck when choked from behind or is it one of those things where it's a tool in the toolbox but when you learn more (krav maga in this case) that you would almost always do something else instead?
It's hard to tell over text on the internet but does it seem like I have a misunderstanding of how the technique works?
