Blank target point of aim?

First topic message reminder :

I'm a little confused, what is your point of aim on a blank target?  This has to do with the first exercise out of the USMC Pistol Team Workbook where it is instructing you to shoot at a blank target to establish a maximum group size.  If there's no reference point or POA then how do you maintain a group?

Ed, 

I have been getting some Rifle coaching from Alex Arrietta (USMC Ret. Double Dist.). One of the the things that we work on in dryfire is to dryfire for offhand at the blank target (white wall, etc) as well. There is no doubt in my mind that it helps trigger control.  Another is to build up to more good shots than we would shoot in a match. Practicing keeping focused for 20+ shots. 

I'm a pistol beginner and my best sustained fires are 95's and 190's. But to do that I have had to learn to accept my aiming area and focus on the front sight while being smooth on the trigger.

I gave up on the center hold when shooting service rifle. It was too difficult *for me* to keep a consistent vertical placement, and the targets told that story in no uncertain terms. Line of white is what worked for me.

Over the years, zeroing to have the bullet impact at the apex of an imaginary equilateral triangle with the top of the front sight as its lower leg has served me quite well. Among other things, it avoids obscuring the lower half of the target.

Well I gave it a shot today. I think I am starting to see its advantages. I was trying some new things today. Working on my hold, trigger pull, and shot process, and having that blank target ( I used paper plates) let me focus on what was going on with the shooter/firearm. Not where the shots were going. And without trying the groups got tighter as I went along.
