4 kids topping all 8 blocks is cutting it fine. Bear in mind the qualification round in this comp is effectively a semi final. 1st and 2nd after qualifiers were separated by 1 attempt on a bonus. This is very close to a tie. Due to categories having to share problems in the final we normally try and get a full separation in qualifiers - which we did, but only just - as trying to separate too many ties in one category in the final normally means screwing over the other category that is on that set of blocs. It also means for the competitors they are less harshly punished by one little slip as if the blocs are hard they have a chance to fight back. Look at the junior boys qualification tour. A really hard tour but they all much preferred it as they knew to make it through you had to fight, not just get lucky/rely on someone else being unlucky.
