For a table version of these diagrams, see the official wiki's outputs here.
If a path's percentages don't add up to 100% (i.e. it only says 60% on coarse), the remaining percent is it staying the same or being destroyed.
Fastest path to O5:
Janitor/Scientist: 1:1 to Zone Manager, Fine to Facility Manager, Fine to O5
Major Scientist/Containment Engineer: Stay on Fine
Any Security Card: Stay on Fine
Coarse and Rough are practically useless unless you want to sabotage other players, would like a specific card, or you want to trade permissions without having the time to set it to your desired setting. (Ex. setting to coarse with a Facility Manager to get a Commander Keycard)
For details on each card, see Keycards.
Conversions without percentages are 100%. If a path's percentages don't add up to 100% (i.e. it only says 60% on coarse), the remaining percent is it staying the same or being destroyed.
Generally, if you want a better gun, stick with Fine.
For details on individual weapons, see Weapons.
NOTE: If one wishes to obtain SCP-207, Adrenaline is not advised to be used as it has a chance of yielding a janitor card, and a chance of nothing at all. It's better to use a flashbang, as shown below.
- NOTE: Although not normally in the game, Coins will disappear on any setting.
Any setting will refine the ammo to next ammo type.
