I wrote something in my CC forum before R2 started, purely because I wanted to know if it was worth grinding the first 18 or not to go lower after making the cut - should have asked the question here.
To me the brief rules summary (the detailed rules page was blank whenever I visited it), suggested the scores would count for the final round only "single-play championship round"... But we've seen similar before from WGT, when all 36 holes counted, hence my question.
Looking at the leaderboard now with R2 is up and running it looks certain both rounds will count, which I think is a shame and misleading... For the record, 4 shots already behind, I had a nightmare in the first 6 holes where nothing went right and WD. Pretty poor effort, but there you go...
Anyway, good luck for those left to play.
