Wheel alignment for 10 years

I had been exerting myself in establishing wheel alignment and axle constructive geometry of the vehicles. Following an officially, I had been scaling only from rear wheel toe value and it's total vector direction, correcting lateral swing. Steering centric position marked on the steering column drifts every time I changed rear thrust direction, the results of scaling value drifted as illusory target, as the later research proved that the fret had been caused by the intended frontal axle constructive design to correct and to compensate the alignment error automatically, so to speak "Self Steer Effect". Moving and drifting of the reliable position of critical reference points have been making it difficult to establish the "Zero Thrust" condition of vehicles for these 10 years. Now I have found out the means of escape from impasse that hit me!
Judging from frontal wheel total toe vector direction with my keen 6th sense while actual running, check and mark down onto steering column "2 positions", straight running position and free no assisted position. Without writing, two positions should be matched as a single point if both positions might be wobbled and drifted on the way, but remember here, the point of adjustment is not frontal axle but of rear total toe direction and it's value only, no any other adjusting point should not be moved however sweet a temptation of the devil might be.
