Back when I was actively trying to "steer" my youtube bubble, it seemed like my efforts took a week or two to take effect; maybe suitably pruning watch history could reduce that time constant a bit? (then there are the paid recommendation slots — those were fairly obvious when I had my bubble over in some other script, but latin-character vids were always pushed in the same placings)
