I've not played the tournaments (rather pointless to play against hundreds of TC's and C's), but I've put in the codes and looked at the leaderboards. Both leaderboards look fine. I assume that as the number of entrants goes over 100 you get the option on the right hand side to see positions 100-200? And will we then be able to see positions 200-300 when the number of entrants goes over 200? And similarly for each next 100 players, or is the leaderboard list capped?
The only thing we don't know (but we never have with any leaderboards) is whether the tiebreaker rules have been adhered to, and players have been given the correct position on the leaderboard.
I would just like to add, asking us to test something and giving feedback is a step in the right direction, rather than making releases with hundreds of bugs. i think you will get lots of support for this if you do it with future updates.
