As for that controversial mahjong round... I'm currently looking like a bit of a fool trying to get a heads-up Hong Kong rules game going at my network, just to see how that one works exactly, while everyone else is of course playing the real games. I came across this paying chart there:

"Fan" (better known as "Han", especially in the Japanese version) is the number of "value points" for your hand. With the help of the 1 Fan Prim's hand would get by winning through a self-draw which we failed to account for, it would be as valuable as the hand I had before, which won through a discard and also had no value per se, but got 1 Fan because I had a fitting flower tile.
But looking at the paying chart above: At least under those rules, winning by self-draw would be considered less valuable than winning by discard, so even if we count Prim's hand, it still wouldn't be enough to tie.
The problem is that there are no standardized rules to look up, since the game is not supposed to be played with two players in the first place. But in light of all that, I think we can let my win in yesterday's live challenge stand.
