When using rule F.4 (Launch & Recovery), it states that launch occurs in the End Phase, but doesn't have anything to say on how to sequence launches when both players have possible launches.

When dealing with fighters and strikers, this is less important, but becomes very important with seekers, especially when reacting to announced targets.

This came up in our game tonight, and we wound up handling similar to direct fire sequencing.  Count up the number of launch capable ships on each side, then the side with more goes first, and launch opportunities are interleaved according to the ratio between the sides (e.g. if one side has 4 launch capable ships, and the other has 2, then the side with four would conduct launches from two ship, then 1 from the other side, etc).

Any official ruling on how this should be handled?
