Oh yes! I was addressing the answer to my first post, that dropping the seatpost both bettered the resisting force and lowered the driving force (the rider on the seat). More insertion is always good for resisting. The amount of post above matters little. All that counts there is the distance seat top (or rider butt when planted on said seat) to seat lug.
