thing to consider (however the top of the swing is reached) if the first intention is to pull the hands/handle & trail elbow downwards although that seems to be what happens in a good swing motion in essence it isn't
as all that's immediately goin to do is have the club seek 'alignment' (physics) with the force the 'arms' - so the top & bottom of that means if the hands(trail elbow) just get pulled goin straight downwards - that 'seeking alignment' sends the clubhead straightways outwards and aways from the hands losing the angles - so contributing to getting the out over the stop situation
good thing to consider when the top is reached don't pull downwards as count-intuitively as that will sound - imagine if the top position is like arrows in a quiver, to get one 'out' you have to pull more level backwards out of the quiver not down
equate that to the golf swing the hands handle initial intention is a ways better if the first direction of travel is out directly 'backwards' aways from target
to do that the right arm will just starts to straighten up a tad - may seem a pretty off the wall set of circumstances I realize but it's absolutely the case
could go into details of exactly why this is the physics of a golf swing, linear versus angular 'work' of the club in the swing with all the different positive & negative kinds of torques being applied (alpha, beta, gamma) but that just generally tends to confuse folks .....
bearing in mind the whole downswing varies someways around just 2 tenths of a sec that initial move of the hands/handle back away from the target is real real fractions then the whole arms/club unit travel down/out & forwards - {after the initial weight pressure transfer of the lower half of the body}
think of it if at a driving range once the movement of the club started in transition so handle direction away from target a point out in the range field - so if the club was let go of it would be propelled directly away from target towards the back wall of the range - if like in an out & over swing the club was let go off then it would be propelled out over the ball/target line towards the range bay divider to the stall infront
