There were only 6-8 top divisions (depending on whether you count different formats in same age group, 6v6, 8v8, 11v11). It's not a bad showing to get to either 1 or 2 top division finals (again, depending on whether you count different formats) at a tournament with only 6-8 top divisions.
So Concorde either made 17% or 25% of the top division finals. Either way, it's not an awful showing. Why would they be ashamed of that?
