How unique is GetMatchmakingTicketResult.MatchId?

The format for GetMatchmakingTicketResult.MatchId is `XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX`.

How likely is another set of matched users to see the very same ID.

I'm expecting this to be extremely low, but I looked in the docs and didn't see anything definite.

Hi, we use .Net Frameworks’ general method “System.Guild.NewGuid()” to generate the MatchId, so duplicate MatchId is basically impossible.

I think there are 5,316,911,983,139,663,491,615,228,241,121,400,000 combinations for a 36-character hyphenated GUID, so it's basically impossible.

I believe you are correct. However, this does depend on how randomisation is implemented. I'm just looking for a little nod from the developers.
