Open wounds, Crushing blow, and deadly strike... Explain?

Basically, what do these three do? I know CB does a tenth or a 4th of HP damage, but I can't find the info at arreat summit anywhere. Can someone tell me what these addons do?
(and do they all work with smite?)

 

[Evrae Altana]

Crushing Blow-chance to take away a certain percentage of an enemy's current life (much like Static Field).
Deadly Strike-chance to do double damage
Open Wounds-causes opponent to bleed uncontrollably, constantly losing life.

Open Wounds-causes opponent to bleed uncontrollably, constantly losing life.

How... much... life?
and how long?

Duration: 200 frames (that is 8 seconds).

The damage per frame seems to be the following (where Clvl is the attackers level, that is the player's level usually):

Clvl=1-15: (9*Clvl+31)/256
Clvl=16-30: (18*Clvl-104)/256
Clvl=31-45: (27*Clvl-374)/256
Clvl=46-60: (36*Clvl-779)/256
Clvl=61-99: (45*Clvl-1319)/256

If you prefer per second, just multiply by 25:

Clvl=1-15: 25*(9*Clvl+31)/256
Clvl=16-30: 25*(18*Clvl-104)/256
Clvl=31-45: 25*(27*Clvl-374)/256
Clvl=46-60: 25*(36*Clvl-779)/256
Clvl=61-99: 25*(45*Clvl-1319)/256
