52% still needed to reach 50% caps?

[nikia]

I remember long ago to cap things like PDT or Cure Potency you would need 52% in gear to reach the real 50% cap because the way SE did math.
I then read a few years ago that wasn't the case anymore but not sure if that is true.

Wondering what is needed percent wise to reach caps like Cure Potency?
Thank you for the info.

There's no clear cut rule, but it definitely is not exact. I remember 51% being enough (just like 26% Haste being enough for the 25% Haste cap), but it depends on the items you use. Some are closer to their described value than others. I used to test PDT by getting hit by 1000 Needles. It's a bit of work, but you'll immediately see if it's enough and how much it is off by.
