Heck, I'm here and I'm not interested in it. This is our first time attending and I'm just summarily underwhelmed.
Just from looking at the performance order, they write this in under each chunk of teams (this is level 4 for instance): Small Senior "A" (19-20 Part) / Large Senior "A" (30-32 Part) Small Senior "B" (5-18 Part) / Large Senior "B" (5-29 Part) Whether or not this was done accurately, I don't know... But explains why some splits were uneven.
