This topic is using the Pole version of Swinging Gate to increase striking power and range. This is more of a fixed gate than a swinging gate but the principle is the same.
This is a control condition where Nage does not use the pole to facilitate the strike. Uke is placed far enough away that Nage cannot reach Uke with the strike.

This is a demonstration of the strike using the pole. Nage inadvertently cheated on this because looking at Fig. 1 and Fig. 3 Nage is closer in the control giving a bias against the Swinging Gate.

The Pole Swinging Gate was also tried on a pole in front of the dojo and the distances measured. Without using the pole Nage was able to step 59 inches. This is much better than Nage did Protecting the Baby. The difference may be that the ground was more level, Nage had been practicing or Nage just felt better. At any rate using the pole Nage was able to step 65 inches. That is about a 10% improvement, the same as Swinging Gate Protecting the Baby. This really surprising. One would have thought that the pole would work much better than the weight. When Nage did the demonstration for the pictures above Nage felt that the difference with the pole was quite dramatic. Maybe a 10% difference makes a very practical difference. Maybe Nage had an unconscious bias towards the expected result and faked it some way.
