This table shows the percentage of players with a given record that have gone on to make the top 8. Data is drawn from all "large" fifteen-round GPs from August 2003 to March 2019. Here "large" means 1537-2048 players. There are 68 such events. Players with byes aren't included until they appear, so a player with two byes who wins their first match in round 3 will count for the "3-0" box but not the "1-0" or "2-0". As such the "1-0" box tallies only people who played in and won round 1. Mouseover or tap the table to show the data underlying that cell.

Here are links to the corresponding tables for small, medium, large, and massive GPs.
