What platform are you running Path of Building on?

Windows

How is Path of Building expected to behave?

When I have max poison stacks > 1, and 100% uptime on that number of poison stacks, I'd expect the # of Poisons on enemy (if not average) setting to default to the average, like it says.

How does Path of Building behave?

When using a skill with a cooldown, there's something wonky about the calculations. To reproduce:

1. Add Explosive Transmutation
2. Add the following custom modifiers:

100% chance to poison on hit
targets can be affected by +1 of your poisons at the same time

Since this skill has a cooldown of 0.5 seconds, it should guarantee a 100% uptime on max poison stacks (you can verify this in the calcs tab, the avg ailment stacks is 2). However, if you set # of Poisons on enemy to 2, your dps decreases. If you keep increasing it to 10, 100, 1000, your dps seems to converge to some value, so either the calculation is broken, or the label is misleading and it's something else entirely.

Now the reason I wanted to set this value to something specific was another support, Arakaali's Lust. I correctly get 16% more damage with the setting set to 2, but then it messes up some other part of the calculation.

Reproduce the issue with Explosive Transmutation, the listed custom modifiers, and the # of Poisons on enemy setting. Start in the poison and cooldown calculation paths exposed by the Calcs tab, comparing average ailment stacks with DPS as the setting changes. Done means the setting behaves consistently with the documented average and Arakaali's Lust still receives the expected modifier.
