While working on fitting McCall's 3935, I started thinking ahead to the next pattern I wanted to sew, McCall's 5475. I figured that if I could get 3935 to fit reasonably well, then I can fit 5475 easily by comparing the two patterns and adjusting from there. So, then I started thinking that perhaps I can approach other patterns in the same way. I'll go through the motions of fitting one pants pattern from each company and if I want to make other patterns from the same company, I can adjust for fit using the first one I made. I guess this is kind of like creating a pseudo-sloper. This is going to be a LOT of work. But, in the end I hope that I'll end up with good fitting pants from each pattern company.
