AIUI the fibres of the leather really do break in the high-stress areas around the sitbones. On a visibly broken-in Brooks, especially a smooth, hard, black one like a Team Pro (B17s usually have a coarse texture that confuses matters) there are lots of fine creases and lines in two areas just in front of the cantle plate. On one of the saddles with softer, more flexible, leather like my old Professionals or my honey Team Pro, the top never develops these marks but doesn't need breaking in, either.
