question about range and accuracy

[keylocke]

is range accuracy calculated calculated when aiming is initiated, or is it calculated when gun is fired?

ie : if pawn aims at target at X range, but the target approaches pawn and the pawn shoots at it at range Y. does the shot calculate hit chance based on X range or Y range?

What do you think would make more sense?

Hit or no-Hit is calculated when the projectile leaves the weapon. Makes sense to me only when it takes the hitrate from that very moment.
