If you think about, it's kinda disgusting how many low rolls must go your way during the career to get a good horse
>don't fail your training rolls
>preferably early Charming event during Junior year+
>consistent Energy refill events throughout career
>inherit extremely low rolls from your parents (aptitudes, URA procs, grandparent skills etc)
>get a specific skill tips under the right circumstances among sea of possible outcomes
>many 3-4 rainbows during the career, especially during the summer
>horse doesn't randomly explode from a forced mood down event or failed roll (slow metabolism from eating, slacker, night owl etc)
>your SSR event chain doesn't randomly decide to fuck off (Swinging Maestro etc)
