I voted "at all times", but in non combat situation it is only used to give a basic visual explanation of how much room the characters have to work with in case combat does break out.
I have multiple mats that I use for virtually every game I play (whether the game is set up to make use of minis and mats or not). I feel that the mat speeds up combat (no need to repeat where everyone is 5 times a round or arguments about how close a character is to another character). I just describe the scene and then place the minis. From there the combat ensues and people can see where everything is. It keeps everyone honest.
As far as metagame thinking. Huh? Its metagame for someone playing a character who is supposed to be a heroic fighter to think tactically? Since when? Of course the player will move to avoid attacks of oportunity, to keep from getting flanked, or to otherwise place themselves in a tactical advantage. A character would probably know a good bit of this stuff and would do the same.
I ran another game, which isn't really set up for mat and mini play, for some friends and they complained at how they went down so quickly. I got a mat and some minis out and they suddenly started to take better advantage of cover, moving to avoid being hit, and generally acting like the combat oriented characters they were supposed to be. While the game was still a challenge, the characters faired much better. That is all the proof I need that a mat and counters/minis enhance the combat side of the role playing experience.
