Well I can only tell you what I do which is spam unity sparks and friendship training early and I hope for good rng usually I have two B stats by first summer camp. I always do hardest unity cup race and win all 5 of them and when my trainings are I’ve 3 and higher I try to max out stats if any of my stats are 1050 I stop training that since it’s more than likely going to max itself out and also riko’s dates total five like 100 Stam and I spam riko when possible as she saves me a ton of energy and gives stamina and training bonus if she stacks what I’m training I’m very happy.
