Adaptable Assualt not adding any melee range.

I noticed I wasn't seeming to get any increased melee attack range from Adaptable Assualt with the node taken naturally or with the jewel. I repeatedly tested Adaptable Assualt for an hour with multiple different skills and weapons and I couldn't notice any increased melee range. I tested it on the stationary sandworm boss in the desert.

PS: This testing would of gone a lot faster if I had a test dummy, also if the tooltip showed melee attack range that would be very helpful.
