For me its situational.
If a deer is meandering / feeding / picking their way down the trail my way, I wait for them to stop, as its very likely that they will based on the previous 10 / 15 minutes of watching them approach slowly.
If its a deer cruising down the trail and I've not seen them stop as they approached, chances are they will not stop on their own, so I will for sure try to stop them for a shot.
If in the first situation, (meandering deer) happens to make it through and approaching my last shooting lane and hasn't stopped like I thought it would, then I'll stop them for a shot.
I draw, get to full anchor, track the deer with my arrow tip, settle it in vertically where it needs to be as I'm tracking it horizontally, and give a soft grunt as soon as I've got my tip where it needs to be. The arrow is usually on its way before the deer is even looking up for the sound.
Haven't had a deer spook from me trying to stop it yet. However, as always, hunting is a never-ending learning experience. So if that monster buck spooks when I try to stop him... my tactics might change
But so far so good.
