» Depots:
Shooting depots effect the guard reps less than the regular faction. So shooting depots after a double bribe will lower your rep with the guard faction less than the Double bribe had raised it. So, getting another double bribe will raise the guard rep to higher than it was before.
Or in other Case, when you've already taken a single bribe from that faction and want to bring it down to neutral again for a multi-bribe, shooting bribes will lower your rep much faster than shooting NPCs, which saves a lot of time.
Shouldn't the word 'bribes' in the bold, be replaced by Depots?
This guide should be pinned, it's really great by the way.
