I'm confused, there are a few different possible methods of "quitting" in Halo Wars.

1) Start Button > Resign
2) Self-destruct all bases & leave all units to die (aka speed up your Defeat)

And once either of these options is performed, it brings up the "Defeated/Resigned" screen, but you still have the option to view the ongoing battle if your team mates haven't finished. Pressing 'A' gives you stats (which are all blank since the game isn't over), and...

3) Press 'B' to Quit and get moved back to the Lobby.

So which of these voids out the points I earned? Once I'm completely defeated, do I have to stay until the game is completed and not press B to quit to the lobby?

I've read that quitting (not sure which method) only voids the 0.2x losing bonus you would have received if you stayed till your team completely loses. But you still keep your base score and bonus multiplied points.

I'm going to pay closer attention to this when I play tonight, see if I can't figure it out.
