Deviation Distance

[Taikei no Yuurei]

So, reading through the manual, I ran into the equation which determines how far away someone has to be for a ranged attack to start having deviation. It is presented as: If the range from attacker to target is greater than Precision/2 – 2 (half the Precision, minus 2) then the missile will deviate from the target.

If I'm reading it correctly, it seems like precision is almost a pointless stat for this part of the equation. For 100 precision for example it is 100/2 - 2(50-2) or 50 - 2(48) or 50-96=-46 so any range greater than -46 will cause deviation? This gets largely canceled out later with the way the amount of deviation is caused is calculated, but that just seems... wrong. 10 precision gives 10/2 - 2(5-2) or 5-2(3) = -1 or greater range.

Am I messing something up with the math here, or is there just always deviation on 100% of shots, and the only thing that really maters is how much deviation there is based on the later calculation for deviation amount? Or, I guess the formula might be presented incorrectly?

You're messing up the math. Higher Precision has a huge effect on accuracy, but with the DRN stuff remember that accidents can, and do, happen.

(This is based on looking at the dom5 executable and the dom6 beta builds a few months ago, it's not impossible that something has changed since)

Things fired with 75+ effective precision do not deviate.

Everything else rolls a d100, if they roll a 1 or 2 they divide precision by 3, if they roll 3-6 inclusive they divide precision by 2.

This thread goes into a lot of other stuff and I posted a mockup of what I think the deviation function looked like when I reverse engineered it, but the kinda big thing is that accuracy falls off a cliff when shooting beyond ((prec/2) -2) squares if your precision is less than 10, or ((((prec*2)-10)/2)-2) squares if over 10.

Practically that means that each point of precision over 10 gives you one more square at near perfect accuracy before things start to go really wrong really quickly. I posted some poorly labelled plots in the thread above somewhere I think.

"Huge" is subjective. While there's randomness in there (including things that aren't in the manual, there aren't (well, when I looked) any openended 2d6s in deciding where something ranged is going to land.

It's not the formula.
The formula is Precision/2 -2
The parentheses hold just the same formula in text form, they're not part of the formula.

I can't believe I missed that they were just spelling out what in words what they'd just put in equation form. Thanks!

And thanks for the other replies, glad to know I was just misreading it after all.
