Cluster nodes Weight advantage and Pressure points interaction

Weight advantage: Atks with Scepter have 4% chance to deal double dmg.
Pressure points: Crits have 5% chance to deal double dmg.


Guys I have a build that stack crit using scepters as main weapon..as the title sais if I have for example 2 pressure point nodes and 1 weight advantage node would my crits have 14% chance to deal double dmg? in other words do my crit stack the 4% of weight advantage double dmg chance with its %? or not? or do they counted differently?

Thanks in advance ;)

As of version 2.17.2, PoB Fork shows that stacking Pressure Points notable work and the chance to deal double damage stacks.
