Oh boy, b4translations but I already recognize the race names because I spent more time playing the game than actually learning Japanese Long text incoming
In the latest training scenario Make A New Track (MANT) you can schedule your own races, and specific only to MANT you can get special character titles by winning specific races which grant bonus stats and/or skills. So obviously minmaxers would want to maximize the bonuses even if it meant inhumane training schedules and gambling on inheritance factors so they can have more races available to run in.
So in this case, they decided for Falcon to inherit a turf gene factor for turf G1s:
Starting with ヒロインウマ娘 (+10 to two random stats) which is winning the Triple Tiara: Oka Sho, Oaks, and Shuuka Sho.
Then, the プリンセスウマ娘 (+10 to two random stats) which is obtaining ヒロインウマ娘 and winning the Queen Elizabeth Cup during the Classic Class (Year 2)
Since they are planning on racing Oka Sho, might as well go for 神速マイラー (get マイル直線○ skill hint), which additionally requires Hanshin JF or Asahi Hai FS (Year 1 only), NHK Mile Cup (Year 2 only), Mile CS (Year 2 or Year 3), Yasuda Kinen (Year 2 or 3), and Victoria Mile (Year 3 only).
So Flash decided they will run Hanshin JF in Year 1 and Miles CS in Year 2. At this point Falcon will have to run 3 races consecutively in Year 2: Shuuka Sho Oct late, Queen Elizabeth Cup Year Nov early, Miles CS Nov late. This is still fine since the penalty isn't very devastating.
Then Flash decided to go for ダートGⅠ帝王 (+15 to two random stats) which requires winning 5 dirt G1 races. Because there aren't a lot of dirt G1 races, they need to start racing as early as possible but Japan Dirt Derby is during the summer camp where it is better to focus on training than racing, and any of the JBC races overlaps with Queen Elizabeth Cup. So that is left with Champions Cup (Dec early) and Tokyo Daishoten (Dec late) in Year 2.
Falcon ended up having to race 5 races consecutively. But that won't be a problem because Tazuna's shady drugs shop sells support items that mitigate the penalties she receives. And we are not even talking about Year 3 and non-G1 titles
