Actually there are three parts to the question.
1). In Wiki, "Each shot beyond the first has Recoil added to the Deviation. Recoil is cumulative, and the two numbers reflect horizontal (left and right) and vertical (up) effects." suggests that deviation is only horizontal. That would mean that the cone of fire frequently mentioned in accuracy discussions isn't true. Has anyone seen bullets shoot below their target?
2). When looking at the deviation of weapons does a base deviation of 0.8 for example mean meters per 100 metres or cm per 10 metres or something else entirely? In the sample calculation in wiki
Prone, one shot, zoomed
M16A2 [ (0.3 * 1.0) + (0) ] * (0.8) + [0 * 0.8] = 0.24 Deviation
SVD: [ (5.0 * 0.8) + (0) ] * (0.01) + [ 0 * 0.25] = 0.04 Deviation
If deviation means metres per 100 metres, you would likely miss every shot with the M16A2.
3). Prone, two shots, zoomed
M16A2: [ (0.3 * 1.0) + (0.2) ] * (0.8) + [(0.1) * 0.8] = 0.48 Deviation on second shot
SVD: [ (5.0 * 0.8) + (2.0) ] * (0.01) + [ 4.5 * 0.25] = 1.185 Deviation on second shot
Is the deviation on the second shot up to 0.48 for the M16A2 or is it always and exactly 0.48?
Some additional thoughts:
In considering accuracy, does movement affect flight path of bullets?
From Wiki, "Deviation Added per Shot: Another modifier, this number is added Base Deviation for each additional shot beyond the first in a given time period, and is cumulative up to the (maximum) in parentheses. For best accuracy, a slight pause between shots is recommended, as this pause “resets” the Deviation per Shot." How long is the pause? Does it vary by weapon?
