Sure and like any process, it is not perfect. There are assumptions made with that saddle and process (mainly that the rider is more like to be in a forward pelvic rotation with lower handlebar setup) which places the rider more forward on the rami than the ischial tuberosities. Even if that is totally correct in essence, the reality is that it will not work for everyone.
And despite the origin of the saddle in the first place (pro’s and women in more aggressive low positions), the saddle has seen wider adoption in positions more upright that may alter the function and placement on the saddle. End of the day, there is NO SYSTEM that can accurately guess or recommend a saddle with anything more than 50/50 results from what I have seen. Actual saddle time and use is the only real way to know, and width is a crucial aspect right along with actual shape.
