Spinning in place...

Quick question:

How exactly does the zero-speed turn option work?

The group I play with has this rule:

If your ship decelerates to 0, it may turn in any direction it wishes.
This
turn is done AFTER the other ships have moved. 

Ie: Turn 1 - Speed 4| -4| Spin
    Turn 2 - Accelerate

This is actually quite handy, but I'm not sure that it is particularly
gospel. Another interpretation	could be: 

You must be AT speed 0 at the start of the turn to spin, thus:

Turn 1 - Speed 4 | -4
Turn 2 - Spin
Turn 3 - Accelerate

Any comments?
