Specifically, so there is no confusion:
The details
The first point to make is that Friends and Schools game classes are completely outside of the scope of the system. These have no effect on Diplomat or Ambassador classes, and the same is true of shorthanded games. In all the ensuing discussions, ‘games’ should be taken to mean Rank and Norank games with a full complement of players.
Also
Becoming an Ambassador
In order to determine if a Diplomat should become an Ambassador, at the end of each game player records are checked to see if any Diplomats have attained Ambassador status.
• Your last three finished games you played from the start are examined, together with any other intervening activity such as other active games or surrendered pickups
• If you had NO SURRENDERS and no more than 3% NMR rate (excluding Builds), you become an Ambassador
But the GOOD NEWS is that one more started and completed game and you are there!
But the good news for the OP is getting one more game started and completed will get you there!
