The format was slightly tweaked for 2007, after complaints (notably from Dennis Taylor) that the system was too random. Matches increased in length from best-of-5 to best-of-7, to give the better player more chance to win. The main tie-breaker for players level on wins was changed, with frame difference now taking precedence over results between the players who are level on points. Notably, under the 2007 format, 2006 runner-up Jamie Cope would have been eliminated in the groups, as he defeated third-placed Michael Holt but had an inferior frame-difference.
