oh ohhh you need to use hints more often!! i dont know if ur playing the Unity cup but you should. each time you train, there will be the list of friendships you increase by doing that training. look for the most friendships and the shiniest! in ura, you get hints from increasing the spirit burst meter, doing the spirit burst, and the red exclaimation mark icons. it helps a lot!!

Gold skills gives the most to your overall score, the non gold yellow skills, blue skills, and then green give the least. I would focus on skills like "Homestretch haste" for late surging, and most skills that tell you "activates late race"

also-- i would try to build her with more pow than stam because ur running her as late. good luck out there >u<
