If multiple players perform the same action, does it go faster?

When performing an action such as opening a safe or disabling an alarm, does it take less time when multiple players are involved?

Solution 1:

It's only faster when multiple players revive their teammate. Other actions, such as multiple people working on a lock, won't speed up the process. Every class does have their own advantages in completing actions:

• Lookout: Climbs up vents and staircases faster
• Locksmith: Unlocks safes and doors faster
• Hacker: Hacks computers and disables alarms faster
• Pickpocket: Jumps into bushes faster

There are a couple exceptions to these rules. If you've completed an action such as entering a vent, staircase, or bush, your teammate can enter into the same area without spending any "working-time" on it.

Solution 2:

Here are some general rules on the "clock dial" actions. These are written from memory and experience and may contain minor errors. It should be mostly correct, though.

• most actions take 3 seconds
• a character with proficiency reduces the time by a factor of 3.
• most actions can be done instantly with a wrench.
• extra characters doing the same action do not speed up the process.

Here are the actions that don't take 3 seconds by default:

• 1 second:
  • entering a bush or tree
  • breaking a jewel case (no "clock dial" is shown)
  • resetting a ringing telephone
  • putting on a disguise
  • opening a scanner "handprint" door under attack by a virus
  • opening an alarmed safe under attack by a virus
  • picking up an inventory item
• 4 seconds:
  • power switches
• 6 seconds:
  • reviving a teammate
  • getting into a sedan
  • getting into a helicopter
  • opening a security "double-locked" door
  • opening an ATM
  • opening a safe

Here's the list of proficiencies:

• Locksmith:
  • opening a locked door (including scanner "handprint" doors)
  • opening a security ("double-locked") door
  • unlocking an ATM
  • unlocking a safe
• Pickpocket:
  • entering a bush or tree
• Cleaner:
  • applying a medkit
• Lookout:
  • climbing a ladder
  • entering a window
  • climbing a staircase
• Mole:
  • breaking a jewel case
  • climbing through secret passages (no "clock dial" is shown)
• Gentleman:
  • putting on a disguise
  • getting into a vehicle
• Hacker:
  • putting a virus in an electrical outlet (note that no other classes can do this)
  • putting a virus in a computer
  • turning off an alarm
  • turning off a security device
• Redhead:
  • reviving a teammate

Here are the exceptions to the other rules:

• reviving a teammate cannot be done with a wrench.
• two teammates (without a Redhead) can revive a teammate in 3 seconds.
• three teammates (without a Redhead) can revive a teammate in 2 seconds, same as a single Redhead.
• two teammates (with a Redhead) can revive a teammate in 1 second.

I have not experimented with other configurations, such as three teammates with a Redhead or two Redheads. I also have not experimented with using a wrench on most 1-second tasks; my reaction time is often not quite fast enough to tell if the wrench was used or not. :)
