Reduced accuracy on Doorman's Call Bell ability is not increased by duration increase items.

What the title says.
If you buy things like superior duration, magic carpet, diviner's kevlar etc, the duration of the slow call bell causes is increased, but the accuracy debuff seems to be independent of this, unaffected by duration increases.
The accuracy also normalizes at three seconds in, even though the debuff says it should last 4 seconds
