It's hard to understand what you wrote, but: 1 + 2 + 2 + 2 = 7, a third level of the perk is helpful even with 1 Strength, unless you are saying that the third level of the perk is broken? For example, throwing knife has 16 range, so 6 ST can be helpful here.Anyway, yeah moved to suggestions.

It's ST*3=max range you can throw.Throwing knife needs 4 ST to operate it properly without penalty to hit. I think with 1 ST and even x3 Heave Ho you'll have -60% to hit with throwing knives, because you don't have Weapon Handling perk.
