 I've done some Googling around, but I can't find an explanation for this.

Just started a game (my second), and have decided to take combat mechanics more seriously and learn a bit about them.  Step 1:  weapons and damage.  And right off the bat I have a very basic question.

I'm still near the beginning of the game, playing a city elf rogue.  He's level 4, str 10, dex 24.  No specialization, so no specialization bonus; no skills bonuses either.  Last night, out of curiosity, I decided to equip various vanilla melee weapons on him and see what the damage score for each would be (by damage score I mean the number that appears at the bottom of the investory charachter screen, next to the crossed swords icon).  I made sure he wasn't wearing any equipment that might provide a buff.  Here's what I found:

Dagger (Base Damage: 4.0):  12.7
Borrowed Longsword (Base Damage 7.0):  10.1
Balanced Greatsword (Base Damage:  11.0):  12.6

Ok, so here's the thing:  I also looked at the combat mechanics formula for these various weapons, and simply cannot get it to produce those numbers.  For example, the formula for single melee weapons is, apparently,

 Damage = BaseWeaponDmg + AttributeBasedDmg + CharacterDmgBonus + OnHitDamage - ArmorDmgReduction

So, for the dagger:
Base Weapon Damage = 4.0
Attribute-Baded Damage =((24+10-20)/2)*0.85*k (where k is the weapon style modifer, a random number 50-75%)
Character-Based Damage=4*0.2

Ok, so the very highest this sum can be is9.2625.  In fact, if you set k=100%, it's still only 10.75.  Where's that 12.7 coming from?

I get similar results running the longsword and greatsword through the formula:  the formula produces are below the number I'm seeing on my inventory screen (7.8 for the longsword, just under 11.8 for the greatsword).

Can anyone help me make sense of this discrepency?  Thanks in advance.

Oh, and one other thing. I can't be as specific about this one, since I'm not at my game computer, but here's the gist:

As I said above, a dagger gives me a damage stat of 12.7 while a longsword gives me a damage stat of 10.1. However, if I dual-wield, using the longsword in my main hand gives me a higher stat than using a dagger in my main hand. What's up with that?

I'd read through that first link before, but never seen the second; thanks!

The second link seems to get at my question.  The implication there is that what I'm calling the "damage stat" on the Inventory page is not derived solely from the damage formula, but possibly from some combination of the damage formula and attack speed.  That explains why a solo dagger beats a solo longsword on my dex-oriented character, but a mainhand longsword beats a mainhand dagger (averaging with the offhand reduces the longsword's attack time enough so that it becomes "better" than the dagger).

That still leaves me wondering exactly what that "damage stat" is, how it's derived, and whether it's worth paying attention to at all.  But that does help, thanks.
