To complicate matters again....
Different saddles allow more or less fore-aft adjustment, and that goes for seat posts as well. Older saddle designs, like Brooks, tend to assume a seat post angle around 73°. If the frame builder makes the seat tube angle steeper, most riders will want to move the seat back to compensate... which is often hard to do.
