Looking at the LOVO video recently posted by Mr. Bean, I think there's some value in clarifying some apparent differences between what is shown in the video and what we actually have in the F/A-18C.
LOVO references a "Dynamic Launch Zone" or DLZ. That's not what it's called in the Hornet, and the HUD indications are somewhat different than what he describes.
This is what we have, called the NIRD (Normalized In-Range Display) Circle. 'Normalized' means that it is a similar display regardless of the A2A missile selected and its range and capabilities. You don't have to do the math for the different missile types, the computer figures it out and presents it in the HUD in a standard format. It's similar to what LOVO describes, but the NIRD Circle has an additional reference point and they appear at relatively different areas on the circle from what he describes.
1 - Allowable Steering Error. Dot needs to be within the circle for the rest of the displayed symbology to be accurate.
2 - Target Aspect
3 - Range to target, relative to ranges below.
4 - R-Aero (diamond shape) Maximum straight line flight distance of the weapon.
5 - R-Max Maximum distance missile can fly and potentially hit with one terminal maneuver.
6 - R-NE 'No Escape' range. You want to preferably launch within this range. Missile should have enough fuel to counter any target evasion.
7 - R-Min Minimum range. Missile will likely not arm or acquire within this range.
8- I dunno. Pointy end of your jet?

#8 is the helpful representation of "close range to here to smush your face into their face"
