Lets try something different then. : )
Map at my time of the question.
Kristina Mladenovic(Gui - Palace 6) has Rui Grain in her palace. Her door is supressed by the Palace, suggesting(both) she won't be at peak state for this as she may have health problems that may not be known(as I can't find info in wikipedia about it).
The Palace is producing her stem.
Donna Vekić(Bing) the formation is worse here. She is nearer to Ding(the Hour Stem that hosts the event), but Ding has its own problems.
Overall form this map would say Kristina MladenSovic may win, but after a problematic match.
Alternatively lets look at the Day Chart. There aren't that many variations for day charts and delay in the match isn't a issue either.
Kristinas position doesn't look very beneficial here. Dona should win after problematical match as there are problems there too.
If Dona wins by a lot without any problems as it seems to be expected then both maps are wrong and need to look something different.
If Kristina wins may be interesting to look more at Hour Charts but with the people stems instead of host/guest.
If Dona wins after problematical match and probably near results day chart may be more accurate.
Of course, while day chart configurations are very limited, hour charts are endless, so if none is correct the good approach is still probably the Hour Charts, however in what exact way may need more experience/examples/testing to be sure.
