Unfortunately, I can't change the structure after the table has been created.
Is it not possible to abandon the table and create a new one? Not that I am familiar with how pokernow works though
As per my estimation, this will take much less time to complete than our league tournaments.
How many hours on average was the 4 league round was? Pretty sure the final table would be way longer than that because of the blind structure and since its a grand finale with decent amount of prizes at stake, most players will be extra tight for sure.
but seriously though, an ideal blind structure would be 10-15 minutes. Anything longer than that just gets pretty boring
