I feel for Charlotte, but I hate to say this, the quality of the women's BMX freestyle is very poor, almost too poor for an olympics, especially compared to the men's.
Hannah Roberts scored 90+ points doing something you would probably see at the local skate park. I don't know what needs to be done, but some radical changes need to be made in my opinion, such as encouraging more points for flips instead of for just sticking your hands in the air going over a jump.
I don't like comparing between genders but the difference in skill level is so stark it is hard not to, especially when comparing the gender differences in gymnastics.
