Dear Mods,

Thank you for correcting and verifying my record. (I forgot that I recorded videos at 30 fps, sry)

And so, I need to know the definition of "click start" frame. I think it's a previous frame of the frame when the Go board appeared. Is this correct, or is there another way to identify it?

Pretty much it is frame right after you click it and you can see the board.

I got it. Thank you for the reply! :)
