But the bonuses you derive from those Attribute points aren't 1-for-1. You need a 4 to avoid a penalty, 7 to get +1, and 10 to get +2.
?
One Attribute point buys one level of Attribute, and Attributes don't apply penalties or bonus in MW2.
Two Attribute are added together then subtracted from 18 to get your base target number.
Attribute only normally go to 6 never 10 with the normal max being Elementals or Pilot who can get a 8 in Body or Reflexes only respectably.
You could possibly get to 9 as an Elemental or Pilot if you took "Exceptional Attribute" but the expenditures for such a choose would leave you pretty lean as a character.Not sure were you are getting all the rest of that.
