Sneak spreadsheet
Minimum sneak-break distance is 3 hexes. With a Sharpshooter perk or having a movement sensor in your inventory its 6 hexes. (If you have both of those - 9 hexes.)
Sneak = sneak skill - all the penalties.
A=2 with the Sharpshooter perk and 0 without it. B=2 with a movement sensor turned on in your inventory, 0 without it. C=2 with a stealth-boy in sneakers inventory, 0 without it. These bonuses don't stack.
D=40 at night (21.00-4.59), D=20 at twilight (17.00-20.59 and 5.00-9.59) with the Ghost perk, D=0 without that perk.
Z considers the impact of time on character's perception:
- Z = 1.2 when it is 9.00 - 16.59
- Z = 1 when it is 17.00 - 20.59 and 5.00-9.59
- Z = 0.8 when it is 21.00 - 4.59
For characters who have Night Vision perk, Z = 1 when it is 21.00 - 4.59
