IMO the "dual strengthening" model of DCNH subtypes (the one that claims that the subtype strengthens both functions of the temperament) makes sense of many of the more confusing forum members' types here. Also it accurately explains some of the more obvious stand-out traits of particular forum members.

For example:

Me: H EIE
Joy: H LSE

Joy and I both have naturally engaged, dominant personalities, and yet we display lots of adaptive, nonstandard type behaviors that have caused both of us a lot of confusion in settling on types. This, according to DCNH theory, is typical of Harmonizing subtypes.

Maritsa: C EII (many nonstandard viewpoints, erratic behavior, has a "spat"-ish kind of behavior, periodic assertivenes and overconfidence)

discojoe: D LSI (emphasis on practicality in both lifestyle and beliefs, enjoys having an emotional impact on others)

Jimbean: C LSI (obviously nonstandard beliefs, confusion with EP temperament)

strrng: N IEI (increased focus on direct logic and harsh judgments of people)

Pinnochio: C LSI (stubborn, often excessively assertive or stubborn, but also holds some fairly out there/absurd beliefs

Ashton: C LIE (can have a blithely over-assertive presence, holds non-standard viewpoints)

tcaudilllg: C LII (nonstandard viewpoints, sometimes commanding and insistant but generally displays behavior consistent with Se PoLR)
