To take a fictitious example, you have 12 qualifiers for the finals.
Pool A: Sharapova-Henin-Schnyder
Pool B Clijsters-Mauresmo-Petrova
Pool C Davenport-Venus-Myskina
Pool D Pierce-Dementieva-Serena
Sharapova vs Henin: Sharapova in 3s
Henin vs Schnyder - Henin must win to stay in. If Schnyder wins in 2s she goes top, in three she is equal with Sharapova. Both women have a stake. Let's say Henin wins in 2.
Schnyder vs Sharapova If Sharapova wins, she qualifies. If she loses in 3, she qualifies. If Masha loses in 2, Schnyder and Henin finish equal, 3 sets to 2 with Masha 2-3. At this point, the rules could say that the winner of the direct encounter qualifies OR that the best games won-lost differential qualifies. In case one, it's Henin, in case 2 it depends on the games tally.
With each group producing a semi-finalist, there'd be semis and a final. The winner would have to play 4 matches.
