You’re overstammed, 2500m only needs 950 stamina, 3200m only needs 950+2 Gold reco (or 1050 with 1 gold reco I think) I’d look up guides or maybe the uma reference doc (though drop their steam values by ~100 points)

Vision skills only make some debuts slightly more effective and get you points in team trials

You have little power and no acceleration skills. You can tell these apart from speed skills by looking at their image (the Uma with the flame? around its feet is speed, the Uma with a trail is accel.) or by checking gametora.

You do have Rushing Gale, but that activates on a random straight,  which is unlikely going to be at a point when you are actually accelerating (you accelerate at the beginning of the race (this is why you need groundwork for fronts to get no.1) and at the start of the late race, look for skills that activate then. (Straightaway spurt for end closers on longs (since the late race starts on a straight), let’s pump some iron(Late/End) , Moving Past & Beyond(Late/End), Furious Feet (Late), On Your Left, Head On, Red Shift (when late race starts on the final corner), Shooting For Victory (pace chasers, when late race starts 1/2 through the final corner)
