Toxic Rain single target - 39% aoe or Anomalous Conc Effect?

I've read almost anything I could find regarding this topic but most of the threads about this are pretty old and all of them seem to imply different conclusions and setups for the optimal overlapping.

What's the best setup for single target overlap?

- 39% aoe with no additional arrows

- 15% quality ACE with no additional arrows and no aoe

- 15% quality ACE with +1 arrow and no aoe

or is there another, new setup that involves phantasmal toxic rain?

poedb says AoE radius is 18. This doesnt seem to fit with the 39% claim. (39% kind of suggests 17/22 radius.)

So likely somewhere somebody is wrong/misleading or there was some stealth change/s.

Or you could test it yourself if you really want to know.

And if the target moves an inch then "the optimum single target setup" may no longer be optimum. Especially not if 'Withered' is applied by the explosions.

I'm using 15% anomalous conc effect with 10% quality phantasmal toxic rain atm. seems do deal more damage than the traditional 39% setup tbh, and frees a passive point+glove prefix
