Why you're almost certainly measuring your groups inaccurately.

Makes sense. By using OP's method, any inaccuracy due to the perceived bullet hole edge on paper and the true bullet width should be eliminated, as long as the error is consistent on each hole. Quick & easy.
Eg |o |o = | o | o
d = d
vs
|o o| \= | o o | where any bullet hole edge error is multiplied x 2
Eg |o |o = | o | o
d = d
vs
|o o| \= | o o | where any bullet hole edge error is multiplied x 2

You actually do have it right, shooting small groups at short to medium distances is a training tool to refine the consistency and repeatability of your shooting technique.
I also enjoy making hits on steel much more than shooting groups, which as I said, to me at least is just shooting practice.
Larger.
They way I look at it is, how accurate are your measuring tools? Do you go out and buy a $1000 guage pin set to know if your calipers are accurate? How accurate is the $1000 guage pin set???
I measure groups from outside to outside only as a way to compare to my next group that I measure the same way.
Precision measuring is a very tricky thing.
Scores, first round hits at increasing distances, distance from aiming point, accumulated distance of all shots from aiming point. Or we could print off chronograph results, and compare ES and SD. Don't even need a range or targets for that.
The ability to put bullets close together somewhere is over-rated by those that think its the same as putting all the shots in the middle, or the only shot in the middle.
There is an entire sport dedicated to the pursuit of putting all the bullets in the center of a distant target. The winner might do it, but probably is just the one who came closest. Everyone there is capable of shooting groups, and just about every rifle there is capable of holding the smallest scoring ring. That tells me that centering the target under varying conditions is harder than putting bullets closer together, somewhere.
No argument but for myself, at 200 yards, punching dead center tru a quarter size dot, one shot is a lot easier than grouping 10 shots touching within the same dot size, in shooting repetability is the hard thing to do, when i set my S&B to be dead center, it will hit everytime after that dead center, i dont mind not hitting the center, but if i was important, i would do it all the time... JP.
You should try F-Class. Hitting the center is the only thing that's important and yet people manage to miss it. You will get your ten shots and a couple sighters. You should be a natural.
Already brought it up in my post in this topic, it's called OnTarget but doesn't work on Mac.
Ol Caramel has stirred up many a thread claiming groups that although great for entertainment value based on the responses, are skeptical to say the least. He has been offered many opportunities to back up his claims by attending matches or shooting with someone credible to confirm what he posts but for some reason that never happens.
Ballistic ae also has a measurement tool for group size and off centre measurments. But I believe those programs use the age old method of subtracting the caliber of bullet which goes totally against the OP method as its apparently totally inaccurate.
Fact is, it's not inaccurate. When overlaying .30 circles on the image and bullet holes. The measurements happen from the outside of the overlaid circles thus removing the odd sized, ragged paper issue the OP is having issues with. To reiterate. If you use an app to measure, it's as close to accurate as you are going to get.

Ah, so here's where all the mensaonians are hiding out. I figured that the firearms community would hold more than it's share of "You people." I guess this is where you guys come to straighten straight 
I can totally see where PR shooting, and to a lesser extent 'reloading,' would be just what the doctor ordered; sort of a 'mental flywheel' and a rev limiter, all rolled into one..
Carry on
