Alexander Grant theorized that for every foot of rod tip off the water, you gained or lost nine feet of casting distance. Example: stand in one foot of water and swing a 13 ft rod, or stand in three feet of water and swing a 15 footer. Given the same line weight, action , conditions, etc, the same distance can be achieved.
Forget the mechanical advantage, or lack of it afforded by the different rod lengths. What matters here is line (tip) speed, stroke length, and height off the water.
The only other thing that comes into play, besides the fact that a line with more mass will keep on going longer (distance) once you get it moving, is physical ability. Some people just can't handle a 16 ft 11 wt rod.
