I suggest performing the trail arm "tuck" at address which will automatically put the trail arm in position. You might "feel like" you are swinging in a very rotational manner, but you're not, and for me that nails the trail arm in the correct position. Look up "right elbow" on YT under Tom's videos. It's invaluable.
@jon - The pictured position with the trail elbow 3-4" off the side of the chest is fine. It is most important to have the upper arms connected at the armpit level while ensuring that the trail arm does not slide back along the side of the chest during the backswing (a motion I refer to as "slot-machining").
The tee drill from the S&T book is a good one for keeping those upper arms connected.

Thanks @Tom! one more thing, during downswing, should that 3-4in gap start closing to where there’s no daylight showing?
