Why would you expect a 50% increase in group size from firing more shots?Good article, and that’s one data point. Authors expectation for match 22 pistols from a rest is 1/2” groups, 5 shot, at 25 yards.
So for 10 shots, perhaps 3/4”?

I personally believe 5 shot groups are more representative of potential accuracy as it eliminates the factor of "Group Chasing"...plus you can shoot twice as many groups to average out your group size. I've found that 10-shot groups are more the sphere of pistols being shot from a machine rest
I would expect most combat handguns to be able to shoot into 2" at 25 yards from a supported position. A 1" 5-shot group at 25 yards might require a tuned CF pistol...or most RF target (as opposed to plinking) pistols. I would expect a Match Grade RF pistol to hold .5" groups at that distance if the shooter has the capability
I would not expect it to be enlarged at all. I would expect the shots to fill in the space between the existing holes.What is your guess, switching from 5 to 10 round groups, and why?
I would find a combat handgun which wasn't able to hold a 4" group at 50 yards unacceptable...that is only 2" off center in any direction from your POA2" is pretty optimistic for a combat handgun. 4-5" is more typical.
5-shot groups have limitations. More shots per group produces a more accurate reflection of the gun/ammo accuracy, and that is the whole reason for the test.

Try adjusting your scope/sights to aim at a point above where your rounds will impact the target. Don't aim at a circle. Try a shape that will offer a definitive aiming point ( like the tip of a triangle) and also offer lateral references. I shoot at 1" squares turned on a tip or an inverted pyramid on a lineI’ve never shot a 10 round group as tight as a 3 or 5 round group.

My SIG P320 will do it, as will my P220ST and P226ST...my alloy frame 220 has gotten loose over thousands of rounds and I'm not sure if it will still hold quite as tightly. My S&W M&P9 wouldn't, until I swapped in an Apex Tactical barrel. The easiest pistol to meet that criteria was my H&K P7...both the PSP and and M8I suspect that you would find most combat handguns unacceptable given your criteria.
I have fond memories of shooting Small Bore 4 Position on my high school rifle team...in San Francisco. More Club competition than anything else. We were shooting the Winchester 52D and Remington 513 provided by the school's ROTCI learned it well when I shot competitively, small bore 4 position, for my college rifle team.
What is considered match grade accuracy shooting with wrists supported, pistol semi-auto 22 LR at 25 yards, ten shot groups
I would find a combat handgun which wasn't able to hold a 4" group at 50 yards unacceptable...
Iron sights, scope or aim point? Makes a BIG difference. 1.5" or smaller 10 shot groups.
