Is it worth it to go past 100% potency?

Ok, I need this settled--how does it work when potency and tenacity stats go above 100%? I know that 100% potency is supposed to make you land the debuff every time, except that there's an irreducible 15% chance of it being resisted (even if the enemy has 0% tenacity, there's always a 15% chance of resist). And 100% tenacity is supposed to make it impossible to be debuffed (except, again, I think there's a 15% chance?). But as if that isn't complicated enough...
What happens when the stats are over 100%? Say I have 150% potency and my enemy has 110% tenacity? Do I have an 15%(100-85) chance to apply the debuff, or do I have a 40%(150-110) chance, or is it something else?
Can someone please break down, in detail, how the math works out when the values are over 100%? Because I want to know if it's worth it to mod a toon past 100% potency. Do I just get my debuffers to 100% and call it a day? Or do I need to mod to say 200%, so that I can still debuff toons with 100% tenacity?
This is all very confusing, and I'd appreciate a breakdown, thanks. :)

potency is just a way to mitigate the effect of tenacity. Tenacity is there to decrease the chance of getting debuffed.
So basically potency does NOT increase the chance to debuff, it just decreases the chance you'll be resisted. If there's no tenacity that increases the chances of being resisted, potency does nothing. There's no difference in the chance to debuff between 0% potency and 200% potency, unless there's tenacity to be countered.
Hopefully that makes sense and hopefully the formula used makes more sense once you're looking at it that way.
tenacity (increases the chance to resist) - potency (mitigates the effect of tenacity) = chance to resist
There's always a 15% base minimum chance to resist a debuff, but there's no base minimum chance to debuff.
It doesn't matter if the toons have 1010% vs 1050% or 10% vs 50%, the chance to debuff/resist remains the same.
