Arranging for the zero lift angle all along the span, which is aerodynamic twist, needs to be in concert with aerodynamic twist, according to Simons, when choosing more camber at the tip..
The difference between the root zero lift angle and the tip zero lift angle determines the geometric washout you will need.
The problem in model sized chords is sufficiently accurate data for the Reynolds numbers the wing will fly at.
Flow breaks down rapidly with lower Rns, as seen in the various wind tunnel data polars, so it's important to keep the Rns where the data looks good.
