What is the value from the calculation in-game?

In the PoB below: 1.42 APS * 6 second Trauma duration = 8.52 expected Trauma stacks.

What is the value from the calculation in Path of Building?

However PoB shows 16% (4 Trauma stacks) under Calcs -> Skill Hit Damage -> MH Total More. Unequipping one of the axes displays the correct 28% (7 stacks), from 1.28 APS * 6 second duration = 7.68.

The same problem occurs with Trauma Support.

How to reproduce the issue

1. Add Boneshatter, or a melee skill linked to Trauma support.
2. Equip one 1H weapon.
3. Go to Calcs tab and find the Trauma stacks in Skill Hit Damage. As expected it's equal to APS * Trauma duration.
4. Equip a second 1H weapon.
5. Go to Calcs tab again, Trauma stacks is now APS * Trauma duration * 0.5.

Start in the Calcs tab's Skill Hit Damage calculation for Boneshatter and Trauma Support, reproducing the issue with one and two 1H weapons using the linked build code. Trace how APS and Trauma duration become the displayed stack count; done when dual wielding no longer halves the expected stacks and single-weapon behavior remains correct.
