Windripper vs Doomfletch prism - why dmg doesnt add up

Hi, i am currently playing an elemental bow rider and using windripper:

I used Path of Building to calculate my potential damage with Doomfletch Prism and it seems that currently it should be the same, but in game in falls 30% down. Considering that i use the same setup changing only the weapon, what might be the case? I would be glad if someone can help.
*Note: my passive tree is in a bit of a mess and i'm testing it on 5l (different colors on the doomfletch), but still the only thing i change is the bow. Endgame doomfletch should be like 40% higher damage according to Path of Building, which doesn't seem to be the case ingame.

My doomfletch:

You're going to have to tell us more than just the two bows you're using and that PoB says the two should perform [X] way.

I know Doomfletch's prism has higher damage potential than Windripper because DP allows for huge returns on every single point of flat physical damage you can add to the build. Windripper does not, and frankly needs to be built completely differently than DP does. Windripper wants flat elemental damage, not flat phys, and is in fact very bad with physical damage, while DP turns every one point of flat phys you can put on the build into three extra points of elemental damage.

The two bows are NOT interchangeable; a build tuned for Windripper will suck with DP, and vice versa.

My guess is the higher crit chance with Windripper is allowing you to shock better.

Shocking an enemy increases your damage by 50% I believe so that's pretty close to your 40% number.

I guess this has been solved already but I'm pretty sure that Doomfletch Prism tooltip in game does not take into account the phys*3 addition of elements.

As has been mentioned, you can't trust the tooltip when it comes to doomfletch. The added elemental damage doesn't show up there, so you get VERY wrong numbers. Have you tried it in actual combat yet? If not, then you should.

Its not the tooltip, thats wrong because he is using pob.

Basically if u just bowswap a doomfetch onto a windripper build, the following things won't match.
Support gems
Jewelry
Inc phys on tree

Also, without godlike phys jewelry and a chance to bleed gem doomfetch does not have any dmg.
