well pretty sure he meant it like this:
take as example your equip alltogether will give you 100 statpoints
from this you take 65-70 determination
and 15 points in bruta and profi
well he is a summy who knows how to play but i still would advise you to stat diffrent

dont feel offendet by this but to me it looks like you are relativ new to this game and i think you will find it difficult to use the selfdamaging in order to fully use the determination (determination = the more damage you get yourself the more damage you do and as a summy you can hurt yourself all the time if you want..emostyle

)
so i would advise you to take profi,deter and bruta on equal numbers (33 points each in the example with 100 points) so playing will be way easyer for you
but in the end dont worry too much about it as long as you dont get Anger equip you will be fine cause you can later freely switch statpoints on your equip with insignias (exept for the name giving one)
