Yes yes, I am aware. Back when yomi was a thing I helped run and manage the international yomi league. This ain't my first rodeo!
As for the time, I'm thinking early afternoon America so that I can pull in the eu evening crowd. That equates to about 7 or 8 am for me, which is ok.
The reason I ask what day people think is optimal (Friday, Saturday or Sunday afternoon) is in the interests of pulling in as many people as possible.
Depending on when I run it, any of those times are fine for me, I just want the max players.
I record things with OBS, which is free.
I am looking into different avenues to stream the tournament.
