If you move 10mm in bone with a genioplasty, how much will soft tissue contribute?

Lets say you move 10mm bone does it in the end move 12/13mm with the soft tissue? I pressed a ruler against my chin kind of like bonepressed dick measurement, and measured until my upper lip and its a subhuman 15mm... @VenatorLuparius you only had 10mm genioplasty but it looked like the end result was alot more

It will look like more. 10mm in bone movements but it will appear like 15-16 due to skin/fat/muscles in the chin area being stretched forward as well.
