Waterfall stacking: Can you leave your tripod and ND filter at home?

After looking and the different stacking methods used in the posts and sending the 3 series through PhotoAcute, I'm beginning to wonder if it isn't quite the opposite: I'm thinking that a small ratio of interruption/exposure times might benefit the character of the movement. In other words: go as slow as possible on the shutter speed and as fast as possible in the burst capture.
