well its a bit outdated since it uses the old training system (i just normal train to kind of simulate the new training system. although, i usually like to token boost my first season, and since im not accumulating BTs by normal training in that system, i cant do that

), but yeah, its a script, and its basically just like building a player. you control the training day to day and SP usage and all that fun stuff. its actually very useful as you can kind of see how build plans will pan out before you start building.
and i would probably advise training on normal this early in your career. light is more for when the ALGs die down and you are working on your last few attributes while trying to finish up your AEQ.
and btw, all i did to get it one up was train speed until SPs+attribute=48 cap, and then capped it. saved more SPs while training speed just above the 48 cap until speed+SPs=61 cap, and then capped it. saved more SPs while training speed just above the 61 cap until speed+SPs=68 cap... ect ect.
