Plus, I figure if ISM is telling people that it will be uncomfortable even if they're experienced with multiple-hour rides, I imagine it'll be even more uncomfortable for me at first. One thing that I do find interesting is that it seems like my hamstrings are being activated more with this saddle. Usually my quads burn out first. The saddle also really punishes you if your pelvis isn't rotated anteriorly. I still feel a little bit uncomfortable on the width of the handlebars, but I'll give it some more time before I change anything else up. As of now, I'm quite happy with the setup!
For the hams, it might be more saddle position and height that help them work. That's what I find. Sometimes on long rides, I'll switch muscle groups, pedal with my quads for a while, then with just the hams for a while. Lower load on your quads is good. Did you also lower your saddle as you moved it back?
