First of all,
clickySecondly, I'm not convinced that guide is great advice, I like getting every stat to at least 50m to bump you above the basic exponential gains formula, though 100m for the merit is better imo - as you unlock gyms if you train with the best dots (gym stats) and up your lowest stats in the gyms with equal dots, you'll roughly hit 50m/stat by the time special gyms are unlocked anyway - which is the main advantage of imbalanced stats
Once you hit that soft cap of 50m that's when you should start worrying about ratios and the like, and typically what's best to keep you relevant is to choose one defensive stat (def, dex) to whore while forgetting the other side, as forgetting one offensive stat will leave you lacking in most fights of a similar weight class (either you'll never hit, or you won't do enough damage to win in 25 turns, which while funny is not very effective :P)
Once you hit billions in your stats and have decent income to blow, you can adapt your loadout to further amplify the stat of choice you whore - a sentinal armour set+wither weapon for def whores, or a delta armour set + slow weapon for dex whores (as an example, but loadout choice is something well beyond the scope of where you're at now, for now just borrow an Arma, dbk and combat set from your facs armoury and call it a day lol)
