Finally returned to something I tried four years ago with more rigor. Front 9 was a bit sloppy, especially holes 6 and 8. 10-13 are terrible though these went well here.

It's interesting all the best times now are Japanese players. I did this on an American GameCube - so I suspect there is no timing difference. Sub-13 is very much possible since my front 9 was 30 seconds behind SoB pace.
