Someone wrote a guide on icy-veins back in august and claimed 22% or 30% or something and the whole community has been talking breakpoints since with nothing else to substantiate this.
There are theoretical points with certain legendaries like the cloak, but even then only if a robot does your rotation with no movement, target switching or anything like that. In the real world, just sim out your current stat weights and go with that, re-sim ever few pieces of gear and do comparison sims with all trinkets to see what is best.
