Any idea how the quality of hit is calculated? (now I've got an account I'll own up to that question) --Parsingphase 16:52, 29 August 2008 (UTC)

It's done at random, and there's been quite a bit of research on the matter if you know where to look. [1]

[edit] pretty maths

btw the latex for this equation is

blob = \left(\frac{1}{tracking} * \frac{transverse}{range}*\frac{sig_{resolution}}{sig_{radius}}\right)^{2} + \left(\frac{max(0,range - optimal)}{falloff} \right )^{2} \\ \\ Hit Chance = 0.5^{blob}

which you can play around with at http://latex.codecogs.com/editor.php or in the wiki's formula editor (although it doesn't like \\ as line break). -- 203.202.21.141
