Rocker can get to be complex subject. Cindy Lou (Egress) does seem to have a little more volume forward in her rocker than typical, but just viewed in static profile. This is because her entry is relatively fine, so I need to drag some volume forward to get her to trim up where I wanted. It's also a bit of an optical illusion. Here stem is basically plumb, so the LWL starts literally just a few inches from the forward most perpendicular, yet the exit is about 3' from the transom. The rise of the buttock in this area is shallow, giving the impression the LWL is closer to the transom, which visually makes the rocker look a bit forward.
Underway, the stern will settle and the bow will rise, particularly as she approaches about 7 MPH. At her theoretical hull speed (8 MPH @ 1.35 S/L), her transom should be just clear with a half load and just touching the water with a full load, unless everyone is standing in the cockpit (except the skipper driving of course). The intersection of the bottom and topside planks at the bow will also be just clear of the water. In this attitude, she'll push past her theoretical hull speed limit a little, because of her fine entry and shallow buttock angles. I suspect this hull will easily reach S/L 1.5, likely through 1.6, before the wave train and drag, truly limits any more speed, without huge amounts of power. With the modest outboard power spec'd for this boat, the speeds she'll achieve, are quite respectable and fuel use will be reasonable. These are the complex set of choices made on this particular hull and you get what you get.
I could have fattened up the entry in plan view, which would have permitted me to make the rocker shallower in the forefoot, but this also means I would have had steeper aft buttocks as a result. It should be noted that Egress (Cindy Lou) does have a fair bit of dry bearing area just forward of the transom, in a static state, that comes to play as she squats underway. This helps keep her trimmed and offers a clean exit as she leaves a pure displacement mode and transitions into low semi displacement speeds. The deepest portion of the rock "belly" is about 18" farther aft, compared to it's static location.
To directly answer your questions Eric, having a significant amount of the rocker's belly aft will cause a great deal of turbulence, right where you'd prefer to keep flow "attached". Ideally, you want to part the water as easily as practical, both form the bottom and sides, then let it "reassemble" as neatly as possible as the boat leaves it behind. If you take Cindy Lou's profile and cock the boat with a 2 degree bow up trim, approximating the rotation around midship(ish), then look at the resulting rocker, you'll see it look much like what your use to seeing. To take it to a higher plane, the increase in forefoot slope, in this attitude, more closely matches the entry 1/2 angles, which helps even out the pressure waves along the entry and trailing aft, so eddy making is reduced to a large degree, especially if the chines are heavily radiused. I didn't bother to run this hull form up over 1.6 S/L ratio, just because I knew what would happen, how much power it would need and the resulting uncomfortable bow up trim she'd have to contend with. In order for her to adopt a 3 - 4 degree angle of incidence for full plane mode, her negative bottom/chine trim aft, would cause her to bow up several degrees (apparent trim), which just isn't practical, though possible with enough power and a skipper in a seat belted chair. Her bow up that high, would cause some aerodynamic issues though.
In the end, when playing with rocker there are a number of things you look at, including pressure waves forming at speed, wave train generation, required volume distributions compared to desired distribution, entry angles, desired Cp and other hydrostatic and dynamic considerations, etc.
There's no best arrangement, with each being "a convoluted collection of discontinuous compromise", made in an effort to satisfy the damn SOR restraints, as best as you can. Mostly you just cuss and pull your hair a lot, as you live with the results.
