Sorry no, Jim, it was meant for genorb, since I didn't quote anything.
Of course a ranked round on the Bo3/5 would add to the total no. of ranked rounds. Alas, this is no proof for it to count towards saturation.
Let me remind you that all the "rules" posted here have been set up by users, there is no FAQ statement or such. Plus they come from the time before the Bo3.
I won't exclude any option until this has been set in bold letters. As I said, there are contradicting statements, and yours is an argument but not a firm proof.
Perhaps I'll have to wait 130 rounds until I'm there ;)
