In my opinion:-
The match was played, even though under different scoring.
Therefore I would treat it the same as a win by retirement, i.e winner counts but the SR does not.
So the winners are Boarder35m and Hotzenplotz on SR1 Shootout (Correct winner)
It's tough, but so are retirements.
Really, that's what my spreadsheet actually said when I just put in Melzer as winner indeed. I will do that. Thanks.
