hi please bear with me for this noob question.

In the Thorograph Analysis sheets, what does it mean when it say something like \"Win #4 at 3-1 or more, Box w/ #8\"? what does Box refer to?

And what does \"Doubles (2x1) with #3\" mean? What is the 2x1 referring to?

And some times it says \"box #3 with #9\", but othertimes just \"box #3\" (just 1 number), what does this mean?

Thanks in advance!
