Shaper of Storms + Unbound Ailments interaction

I leaguestarted Ignite Eviscerate Elementalist and have generally had a really good time with it. However, there's something that I can't figure out with my shock effect which I'd like some help with.

I've attached a POB, but I'm using Shaper of Storms, with Unbound Ailments in my Eviscerate links. With my current Non-damaging ailment scaling, I'm getting 32% shocks from effects like Tempest Shield (25% *1.3 from effect on tree). When it hit boss with Eviscerate I should have 46% shock effect (25% *1.84 (30% from tree 54% from Unbound Ailments).

But this seems really inconsistent. I was under the impression that the largest shock should apply to the target, but sometimes it seems they keep their 32% shock from Tempest Shield and Eviscerate doesn't shock at all. If the boss hasn't been shocked by Tempest Shield, they get the full 46% shock from Eviscerate.

I'm judging shock effect from the UI under the boss healthbar, so maybe it's a visual bug only? Or maybe Shaper of Storms is only applying with hits against un-shocked enemies? Is there something more to this interaction that I'm not understanding?

Not sure if I can share PoB here. But I have a link if that's helpful.

Not really sure, I took a look at the POB but I don't really understand it. The damage calculation seems to be not including the effect of unbound ailments.

On calculations tab, Shock effect value, 1.84 is counting it, but below that, current shock, 32.5, seems to be using the 1.3 value, with tree nodes applying, but without the unbound ailments. This value is being used the the dps calculation. I tried with stormbracer boots, and same thing, applied to shock effect value, but not the value used in the calculation.

I don't know why that would be, or if it even relates to what you are encountering in game. I tend to think it should apply how you are expecting it too, with the shock of eviscerate overriding TS at a higher value.

I don't have much experience playing shock builds, perhaps someone else is able to explain.

The way I thought it worked, before reading the wiki or POB, was that is just set shock values lower than 25% to 25%, but they seem to say it can scale.

Bump. Does anyone know about this? My Elementalist is not using that ascendancy currently, so would take a bit of work to figure it out.
