If, as it seems, there is no need to cut the number of games played then maybe consideration could be made to the following suggestion:

Perhaps we could have the finals played as 1st vs 4th and 2nd vs 3rd, then the winners play in the final and the losers play a 3rd place match?

There is a scenario that crops up fairly often using the current system. The scenario is beating the same team three times in order to win the grade. First beating them in the rouind robin stage, then beating them in 1st vs 2nd match and then beating them again in the final. Or worse still, beating them in the first two games and then losing to them in the grand final due to unforeseen circumstance, like connection problems or player availability!

Worthy of conideration?
