Damage cap after level 20

[Stinxer]

Hi all, I recently rolled a warrior and got him some pretty cool weapons. When I got to level 20 I expected to be hitting like a truck with the Oggok Cleaver which is 44/60 for those who don't know, well for some odd reason my max damage at level 20 with this weapon is 60 which is confusing to me because I thought all caps were supposed to be lifted after 20. The following URL from the P99 wiki says the same thing http://wiki.project1999.org/index.php/Game_Mechanics and here is the actual part that says it.

Weapon Damage / Efficiency

Weapon damage can be figured by using this formula:

Average_Slash = (2 * Weapon_Base) + Bonus_Modifier + STR Modifier

Damage Cap

Damage cap = (dmg * 2) where dmg is the weapon's stated damage.

levels 1-9 - damage cap is 20
levels 10-19 - damage cap is 40
20+ - lifted, can do 2x weapon damage or more based on class

The dmg*2 formula is true until lvl 28 where you get 1 bonus damage every 3 levels to your main hand attack. So at level 50 you get 8 extra bonus damage:

main hand = (dmg*2)+8
off hand = dmg*2

That's why a fast weapon can perform as good as a slower weapon with better ratio. For example, a dragon spined claw (10/21) only outdamages a revultant whip (5/14) by about 10% or maybe a bit more (that's my personal parse). For off hand, you need the best possible ratio (no damage bonus).

If anyone has any insight on this, it would be appreciated.
