OK. Bridging should have been easily right on the rail, unless your rails are quite skinny.
Based on what you did on those three balls all down along the side rail, you had 3 very different cut angles. The first ball was lined up to the left tip of the side pocket and the third ball was quite a distance away up the opposite side rail going toward the corner pocket. You used the exact same cue tip offset distance on all 3 shots and pivoted back to CCB on each.
As you just posted, ALL 3 shots went into the pocket. The balls didn't track differently. They all 3 went into the side pocket.
I guess it's time for you to try twisting it into something else and say otherwise.
