How do you bracket your exposures?

Guillermo Lujik about exposure bracketing for HDR:
He an others propose to have quite large exposure intervals (e.g. 3-4 stops), meaning that most interesting scenes can be properly captured by few brackets. The available camera DR will be limited to some degree by lens glare anyways (a post by Jim Kasson)

So if todays best cameras offer a DR of ~14 stop at base ISO, lenses (in one instance) at best allow for ~20 stops of DR and brackets can be spaced by 3 stop or more, how much exposure bracketing is really beneficial?
Of course, as a Canon user I can only dream about 14 stops at ISO100.

Guillermo Lujik about exposure bracketing for HDR:
*Your least exposed shot preserves the highlights of interest (ideally highlights should be just about to start clipping = ETTR)
*Your most exposed shot produced a sufficiently high exposure in the deep shadows of interest to get acceptable noise there with your camera
*The EV interval between your shots can be properly handled by your fusion software (with ZN this gap can be 3 or even 4 stops)

"Based on simulations, the Canon 20D can record nearly 20 stops of dynamic range using HDR imaging if only a point light source is present. If half of the field of view is covered by an extended source, then only 9 stops of dynamic range can be recorded by the 20D..."
