Good job Kim.
I haven't seen the match, only the statistics, and I've noticed than Mauresmo had a lot lot lot of unforced errors in few games ( 6+1+6+4 = 16)
And before the rain delay, Mauresmo had 0 winners to 10 unforced errors in 3 games (Kim won 13 points)!!!
So I don't think it was that difficult for Kim
