@Tamnymore it's not. Rather dumbed down pattern drafting, all told.
I tend to draft for myself from 1930-40s blocks...I fit the beauty standards of the 30s and 40s with wide shoulders and thinner hips and I don't often have to allow for shoulder pads or with very minor tweaks. Not quite an inverted triangle, not quite an hourglass . My husband is a trapezoid/apple and his tend to do well with more modern drafts, while my son does well with the late Edwardian/Early 1920s as an inverted triangle.
My shoulders are as broad as my husband's, so I don't have much issue with the shoulder draft except that I have to account for the seam being too far to the back. Wide in berth not front to back. I usually have to dart my shoulders along with my T-rex arms needing to be shorter.
Sandra Betzina doesn't usually fit me without major adjustments that I have to do more of than the usual big 4 blocks...which mostly fit with pattern walking to correct some of the basic drafting errors and the massive ease...so there is no real one size fits all with sewing for anyone.
