I like this better because you don't have to remember whether it's the attacker or defender that needs to be even for the adjustment to apply.

I haven't really followed here, but if you simply took the delta of each from 10, halved it, and don't round on the charsheet ( So DX 15/+2.5) and just carried that modifier, you could decide to either round fractions up or drop fractions, but if you're doing 2.5 - 1.5, that's 1.0 and it takes care of itself. Yeah, you have the 1/2 number on the charsheet, but you only have a subtraction to do, and then you can decide round up or drop fractions. Round up favors the attacker (which is more true to the proper TFT rules which favor attacking) drop fractions favors the defender. Both simple.
