[1-X]

I split people into four seeding pools based on their scores in round 1. The four highest scorers became the first seeds in each new group etc. Random.org decided the others, with redraws to ensure that as few people as possible are in a group with people from the round before.

The top two in each of these groups will go through to the next round. In the event of a tie, the player with the most bonus points will qualify, and if they're even too, X+G, whoever scored most on the last day and so on.
