1) Well, yes it is a momentary distraction but if you are seeing it bad enough it can sort of hurt your eyes a little if the flashes of RBE are bright. If you are watching too bright of an image, when you see it is sort of like someone taking a picture of you with a camera flash that has rainbow color (not quite that bad, but you get the point). Most of time you see it as a flash in the shape of a line or square or circle on the screen after fast moving motion in a dark scene with bright lights.
2) The best test is just watching content or taking a PC with a black desktop and moving the mouse fast. Stargate Universe series is a good test because it has a lot of bright lights in dark scenes. Pretty much any scene with bright lights in dark scenes, like car headlights at night coming towards the camera or the ending credits of a movie. That is what causes it, high contrast shots. That said, the only way you'll know for sure if it bothers you is by spending a few days with it usually, otherwise you can make the wrong judgement fairly easily.
3) It depends on what Hz you are in to how fast the exact number of rotations go by per frame, but the rotational speeds themselves get to 15k+ RPM just like a HD motor (actually there are some slightly faster). The number of rotations is just calculated by how many times the same segment goes by per frame. The more segments you add does not cause a different speed, it just means higher segments is better because the amount of time the wheel spends on each colored segment is shorter. For the w7000, the max speed is 6x in 60hz, and 3x in 120hz. The reason you say 3x in 120hz is because twice as many frames go by in relation to the number of rotations of the wheel, but the RPM of the wheel is still turning at the same speed. The number we go when comparing different color wheel speeds is the 60hz mode, which is why the w7000 is a 6x wheel. You can change the color wheel speed in the service menu. The color wheel speed in 3D and 2D by default is 4x unless you change it in the service menu, but even the actual RPM speed changes slightly between 24p and 60hz mode (hence you can see slightly more RBE in 24p modes).
4) Yes, the IRIS can be audible but I suppose it depends on how quiet of a unit you get as there seems to be a unit-to-unit variance.
5) See Answer # 3.
6) Well, you can see RBE when bright whites and dark blacks mix mostly, but sometimes you see it on a plain black screen as well even with no objects on the screen (even before the credits roll for instance).
