Total KD chance slotting Burst with Overwhelming Force and Superior Avalanche chance for KD?

[StarSeven]

Total KD chance slotting Burst from KM with Overwhelming Force and Superior Avalanche chance for KD?  Any idea what the total %chance would be with no other recharge so just the 23.2% recharge from Superior Avalanche, and does slotting both these enhancements cause any unintended, undesirable interactions?  I know sometimes OF will do that. 

 

Not sure my math is up to the task.   

50% Burst KD

20% OF (not PPM correct?)

~46% Superior Avalanche? 

 

Are these distinct events or not?   

 

 Would it be like a 78% chance of KD occurring or am I totally off? 

 

Also, Could this cause KB if multiple proc?  even with the OF slotted?

If two or more activate, they will cause knockBACK rather than knockDown.  Knock is additive, and two or more applications of +0.67 knock gets you over +0.75 knock which causes knockback.  Even with the KB to KD, since the mechanic that seems to use is divide the inherent KB value of the power by 10, and then the additives of the procs get you over the limit.  I tested similar things a while back, and I honestly don't remember if the order of the procs in the power matter or not.

 

And the "proper" way to look at it is to look at the probability that NONE of them trigger, and use 1 - that probability to see your chances that one, two, or three knock triggers will occur.

 

Also, according to City of Data (all hail @Uberguy) the OF proc is 2.5PPM.  The 20% straight probability is a bad label.
