Weapon sharpness factors don't seem to be working

[Pendulum]

From Karjus' post on "Weapon Damage Factors", it's mentioned:

Additional Weapon Factors
Keen-Edge - 20% bonus to DF. IE, a Shortsword becomes 0.96 while a Glaive becomes 1.08.
Material Sharpness - X% bonus to DF based on the Sharpness factor.

However, I tested it with three keen-edged rapiers, and this is what I got for max damages:

• Metal / Pierce / Slash

• --------------------------

• Iron / 96 / 108

• Bronze / 96 / 108

• Steel / 97 / 109

This doesn't seem to add up. If the Iron rapier is doing 96/108, then the bronze should be doing (at least) 97/109 and the Steel 98/110, if not a bit more.

I can run the math in a bit, but I recall DF math moments of mine where the number expected was one off due to fine number rounding down.

[Pendulum]

Right, but if that were the case, wouldn't the result from all three metals be flat identical?

[Squeak]

I'm no math whiz, but it'd appear all calculations round down, or just drop off the thousdanths, for end damage.

Doing the calculations off what is provided, I got:
Iron: pierce (.8)x(1+.20) = .96
slash (.8+.1)x(1+.20) = 1.08
Bronze : pierce (.8)x(1+.01+.20) = .968
Slash (.8+.1)x(1+.01+.20) = 1.089
Steel: pierce (.8)x(1+.02+.20) = .976
Slash (.8+.1)x(1+.02+.20) = 1.098

Which would result in the findings you got yourself.

Wanted to add on that material sharpness IS definitely working - a melee attack with my flint javelin only does 76 piercing damage, while a melee attack with my bloodglass javelin does 105. It's just not a HUGE bonus at lower levels of sharpness, since it's a % increase (similar to heft - practically speaking, there isn't much reason to use a sling bullet made from a material with a higher heft at the moment, because a 2 to 3 % increase on damage from a sling just isn't that much).

It's possible the numbers have been adjusted at some point though (whether that be weapon damage caps, or the actual benefit of sharpness) without the documentation being updated.
