Real Talk - How exactly do Procs work in Whirlpool?

[Willdabeastalt1]

Sorry if this has been answered already, my best googling has failed to find an answer that I'm satisfied is current, since a lot of proc posts are outdated following changes.

 

So I know Whirlpool can be completely filled with Procs ... but do they actually proc?  Each of them?  How often?  It's a patch pseudopet which I understand is an incredibly low rate, but some people were talking about a bonus proc on initial cast, is that based on the actual recharge time or the 10/10 patch proc rate?

 

Short of actually building a Water Corruptor/defender/blaster it would be nice to know if it will actually work.

Any true help would be appreciated!

The proc bonus on the initial cast of pseudo pets seems to be based off of the power's recharge time and then becomes ten seconds afterwards.
