This technique should be fine if the DC restoration is good or bad, because the usual test patterns (gray scale or color bars) have constant average current in the three guns. But, on regular video, when a scene has a lot of one color in the highlights, the DC restorers have to work to counter the change in average currents between the guns; so when you have a face and yellow hat filling much of the screen, the tracking gets pushed towards blue if the DC restorers are weak. I think replacing that tube would be worth a try.
