Shortcuts?? I dunno. I'm no SF specialist, but I'm guessing it has something to do with training OD early when he is young because there are so many skills to train. Also train JR early because an SF needs JR also, and JR will train a bit of JS. Then train IS, ID,JS and REB, and pump 1on1 for some time. At the end some PAS will be beneficial.
Also it is much better to have an SF who has all skills low but solid(like proficient) than to have some skills at tremendous and to have holes in some skills like mediocre or such.
