A couple of observations.
The blade in that video is leaving a lot of growth. The reason I point this out is because it takes more than one or two passes.
It is important to remember that straight razors were used by professionals where going is several directions is less of a challenge than when a man is shaving his own face. IMO, it is better to just get the best you can as safely as you can. If you are not satisfied with the SR, use a DE or SE to supplement.
