Just played real time for the first time and I had some questions.
1) when you call stop, how much time do you have to state what you are going to do? Do you call stop and then can you debate with your team about which space to shoot your torpedo with? We took to setting a 30 second timer after calling stop. Likewise, if you use sonar, how long does the enemy captain have to figure out how to respond?
It should be immediate. We call stop, announce what we are doing and then target space if applicable.
2) while stopped and waiting on the other team, can your team discuss strategy?
There shouldn't be enough time if you apply the above answer.
3) is there a good method to differentiate the captains movement orders from general discussion? We had cases where the captain was discussing if it was better to go north or south, and then declared south, and the enemy radio operator didn't know if it was one or two south movements.
This is a problem we have run into as well. part of it is announcing in a clear voice or state "Head xxx". We have tried to eliminate discussion of direction and just point silently until ready.
4) it seems there is a big advantage to a team who can move rapidly. Can each team move as quickly as the captain can call out orders and receive the OK?
As quick as you want. This is why I think real time is better than alternating.
