Emily is very consistent, but is struggling against the top players at this level - thus she looks like fitting into the 400-600 ranked bracket.
My instincts are that Emily is capable of rising much higher than that if much fuller focussed on tennis. With all her other sports and studies that certainly can't have ben the case until now, however well she compartmentalises things.
Can you to be too good at too many things ??
Be interesting how college goes. I imagine at least sportswise it will then be very much tennis, tennis.
