Character Builder (Swordmage) -- Why do it like this?

[Jeff Wilder]

The swordmage has a class feature which provides +1 to AC when using a two-handed weapon, and +3 to AC when using a one-handed weapon.

The CB adds in the mods (in AC) as either "+2 misc, -1 misc" or "+6 misc, -3 misc."

The results are correct -- either +1 or +3 to AC -- but can anybody tell me why the CB does that, instead of just "+1 misc" or "+3 misc"?

My guess, and I emphasize this is only a guess, is that the miscellaneous bonus is only defined in twos - +2/+4/+6. The miscellaneous penalty however is defined in ones. I agree it's a little wonky.

But then, why not use +2/+4 (depending on your off-hand) and a fixed -1?
