Production and convoy questions

[WallysWorld]

That is true not knowing where the enemy forces will move to that turn. I've been caught off guard more than once by an unexpected enemy move.

Another question, if you don't mind:

1) Does it matter the size of the force set to patrol an area in order for the base to build up its planes and supplies? Or will 1 single ship on patrol do the same as 10 ships in a task force assigned to patrol? I'm asking just in terms of building up the base.
