Top 2 from this weeks lead ups get invited. Plus the Chariots winner means still 3 invites leftover. That leaves plenty of leeway for a star having a howler or missing the start to still be invited.
So what Kung Fu got invited first, the two lead ups this week give the best chance of getting the top 8 into the final field regardless of the order they are invited. Its not like Lazarus is going to miss out on an invite and we are blessed to see him go around one more time so whats the problem?
