That would be the reason the white-list is relied upon in any configuration.
Though as Jowa pointed out in the other topic the default settings do not enable some settings featured in the
proactive configuration.
As such it would be rather counterintuitive to assume the white-list as a reason that prevented to achieve 100% .

Thanks for the clarification. It seems the white-list may not be the reason for Defense+ not achieving "100%". Rather, as you and Jowa have pointed out, it's probably solely because of using the default configuration.
However, as I said, Defense+ is highly configurable - setting it in Proactive configuration (and perhaps some other tweaks) is one way to configure Defense+ to achieve "100%" in any test.
