Yeah yeah, "strategy"
It doesn't matter if the Senpais totally dominate and outplay the Traps in their matches but ultimately lose in the long run because the Tsunderes and Lolis decided to stall out their matches to farm up more Victory Points instead of actually trying to beat each other. Having an RnG element (Tay's Decree) determine how much time teams have essentially makes teams "strategize" against the game, and not their opponents, thus ruining the integrity of the competition.
TL;DR in an earn-as-many-points-as-you-can type of game, everyone should have the same amount of time to farm up points.
Edit: though i do remember Ren saying that the winner of the tournament isn't based on Victory Points anymore, but too lazy to search thread for it.
