Same as Clark. I used to be 6 ft (

), but have shrunk nearly an inch over the years, and my optimum LOP is about 14 1/4 inches.

How you mount the firearm is critical. I have a short neck and shoot heavy DRs with the butt-pad on my pec, but many shooters place the butt-pad back in the shoulder-pocket and stand a little side-on to the target. Big difference in LOP.

Reminds me of a story:
Mate's girl-friend wanted a shot out of my AH 20/.577 double. Insisted, in fact. She normally hunted pigs with her own Win 94 .44-40, and didn't want to look sissy in front of the boys. To my horror, she mounted the steel buttplate out on her arm some 2 inches from the shoulder-joint! I tried to get her to mount on the shoulder, but she wanted to do it her way! Insisted, once again! Well, the first shot ripped that buttplate down the inside of her upper arm, with obviously painful consequences. Tough lady: she insisted on the second barrel, and mounted it exactly the same way!

I saw the ugly purple and yellow bruise 2 days later, at which point she admitted to being perhaps a little hard-headed!
