I'm often surprised by the difference between how i expect a weapon to perform in NCTH, and the way it really does. I was happily playing UC, when i realized that on a target that was pretty far (about 19), my brand new rifle (Vepr-308, accuracy 53) was not giving me a better aperture than a simple Agram 2000.
So following Headrock's advice from the HAM thread, i decided to do a proper testing, to get truly comparable apertures. So i've used the same Merc, in a stable state, against the same targets.
Methodology
Version : UC 1.13 RC 5 + HAM 5.4
Merc : Morgan (MRK92, AGI73, DEX88, LVL4)
[Note : As this him HAM5, DEGREES_MAXIMUM_APERTURE = 13]
Target #1 : Range 18. Target has moved, probably all its APs. Purpose was to get data at typical engagement distance.
Target #2 : Range 23. Target has moved, but probably less. Objective of this second target is to compare weapon behaviour at maximum visual range. At this range, i expect a rifle to be more precise than other weapons.
For both targets, Merc is crouching [except the second try with the Vepr].
I've listed for each gun its Aiming Cap modifier, and other modifiers in brackets (if applicable).
Finaly, i've divided the weapons in three categories (bad / average / good) simply to
Poor Accuracy
Weapon details :
Toggle Spoiler
Makarov : 0%
Skorpion folded: 0%
PM-63 folded : 0%
Skorpion extended: +5% (+3 flat aiming)
Average Accuracy
Weapon details :
Toggle Spoiler
Vityaz : +10%
PM-63 extended : +5% (+3 flat aiming)
Agram : +10% <<== Don't know why... Is it considered long arm ???
Vepr (crouched) : +10%
Colt : +10%
Good Accuracy
Weapon details :
Toggle Spoiler
AKMSU (kobra sights): +20% (+15% snapshot, +10% target tracking)
MP5 : +10%
CAR-15 : +7% (+5% snapshot)
Vepr (prone) : Same, except than Gun handling is down to 4
Magpul : +10%
Analysis
x Significant CTH difference between the Makarov & the folded skorpion, despite accuracies that are very close (3 vs 5). I now remember headrock's comment that "accuracy is somehow logarithmic"
x At range 18, the Agram has similar CTH vs the Vepr rifle(crouched). At range 23, the Vepr has an advantage, but his CTH is not very high (probably 1 hit every 3 shots). Its only advantage vs the Agram is the caliber (7.62 vs 9mm)
x Compare the MP5 sith the Colt SCW. The colt has double the accuracy (40 vs 23), and double the gun handling (8 vs 4). End result : the mp5 is more accurate at all ranges
x The Magpul PDR is the most accurate gun, at all ranges. 47 accuracy and 1 gun handling is the winner.
x Despite having a lower accuracy (23 vs 27), and lacking the bonuses from the Kobra sights, the mp5 ends up being slightly more accurate than AMSU. 4 vs 12 GH....
Conclusion
x Within visual range, high accuracy is overkill. 20 is enough to get a good CTH at range 18 (cf mp5). I'll do more checks to see which is the "right accuracy before overkill" at range 23-24, but my guess would be around 30.
x Once a minimal accuracy (20) is attained, gun handling is the most important predictor of actual CTH (for the same Merc...)
x I'm going to sell my Vepr...
And finally, kudos to Headrock for bringing Gun Handling in UDB

I think the only way to check how much effect accuracy has at each range is to screenshot the aperture, then change the gun's accuracy to 100 (perfect) and check again - to see the difference.
BTW, showing accuracy as part of the targeting cursor is something I was never too sure about, and eventually ChrisL and I decided it would probably be better to do so - but it is still somewhat misleading. When shooting, accuracy is applied AFTER the muzzle has been moved - so you can't really add it to the shooting aperture and get any sort of accurate feedback like we do today.
Here's the problem:
In this picture, the red circle is the shooting aperture as we see it today. The green circle (sorry, I failed to make it more visible, so zoom in) is what the aperture circle would be if we removed accuracy as a factor in determining the shooting aperture size (as displayed on the cursor).
The yellow area between them can only be hit if the muzzle randomly ends up being pointed sufficiently close to the edge, and the bullet is then randomly calculated as flying away from the target. Again, note the use of the word "random", because we've got two random factors at work here.
In other words, even if the muzzle ends up being pointed near the edge of the green circle when the trigger is pulled, there's only about a 60% chance that the shot will go outside the green circle at all. The lower the gun's accuracy, the larger the yellow "discrepancy" area will be.
I'm not sure exactly what I'm trying to say here, but I can tell you that basing your experiment on the size of the shooting aperture is... probably not the best way to do it.
