FYI: Conditions for a game ending in a Draw

Team A pushes crystal to 50% checkpoint, but no checkpoint progress is made.

Team B pushes the crystal back to Team A's 50% checkpoint, but no checkpoint progress is made.

Team A and B fight it out while the crystal is somewhere between these two points and the game goes into overtime.

Team B pushes crystal back to the 50% checkpoint again but wipe before they can make any checkpoint progress.

Game ends in a draw.

Update in the replies as new information changes what I know.
