i never play under those conditions myself - new 860 cloth, new balls, massive lights above the table - so i can't go by my own playing experience. i also don't have the stroke chua possesses. so then the question becomes whether i think chua can achieve that cb action with the amount of cue speed he seems to be hitting those particular shots with. which imo is difficult to assess. you also can't just hypothetically replace the guy with one of the best strokes in pool with faceless nameless players.
what i can say is that it does look suspiciously effortless relative to the action achieved. and if JJ, whose job it is to watch and analyze all these matches, says it looks anomalous, than that weighs heavier than whatever i think.
