Zero Thrust completed

Straight running steering position indicating mark on a handle column would be removed today, because BC7 SUBARU Legacy LSi US model does not desire to monitor any wandering phenomena any more, yes, zero thrust adjustment has accomplished at last with persistent efforts lasted as long as 10 years. Now, I have acquired how to do that in details. As a conclusion, any specific habit dose not exist promptly, in another words, any habit could be eliminated by precise adjustment in not minutes area but in seconds one of angle value of thrust. Even one minute discrepancy in thrust angle could cause lateral wondering habit while straight running, probably plus minus 10 seconds would be some acceptable tolerance?
Once established the "Zero Thrust" condition in thrust angle, completely different world would be waiting for a lamb wandering around everywhere like me.
