How is merchant speed affected by panic?

[hachiman]

Hello

So when a ship in a convoy is hit, I believe that an automated program I call Panic Mode is initiated. In Panic Mode the ships scatter and also increase speed.

After 10 minutes or so they settle back into convoy columns again(unless further attacks happen during the panic period which means the increased speed is maintained) and resume their old speed.

What I want to know is, is there a set formula for Panic Mode Speed?

Do the ships

1) Stay at the old before Panic Mode speed.
2) Do they increase speed by a certain multiplier like x1.5 or 1.75 etc
3) Or go to their max speed
4) Or is it based on something else?

Answers appreciated
