I brought you also math to show you that it makes no big difference.
10% is a very big difference, that's the difference between Ag30 and Ag40, more than half the spread of standard starting characteristics.
Anyway, the point is: the guy with Dodge 50% (not something to sneeze at) only has a 30% chance to evade a guy with BS40 (note: lower than your Dodge!). I would feel pretty gipped if I were Mr. Dodgy seeing more chance to dodge almost halved.
