If you look around on the Internet you find these are variations on illuminated reticles for tactical scopes. There is no Mil logic scaling in the structures related to WW2 air combat Other than the main ring is roughly 100Mil. The cluttered structures are going to cause you issues at times resolving your con from ground clutter during low level maneuvering. These gunsights just look COOL for those inclined to that. You might see them in some of the more popular FPS Special Ops style games on the Internet.
The foundation for the reticle structures are modern military Mil Dot scopes and reflex Holo image sights with advanced ranging ladders for fixed position shooting. I use a Mil Dot scope with my NM M1A1.
Most of your shooting in the game requires you to lead by about 20-50Mil while holding elevation of about 14Mil. The default ring for most countries was 70-100Mil to achieve two results. First to gauge distance based on the relationship of the ring to the con. Second to aid in Low-E turn lead estimation to shoot in front of the con. Here is a link to an excellent article from SimHQ to help with air to air gunnery in Aces High.

Then an angle to dive at along with a speed that will make the marks usable.
The way to discover the marks and speed is simple. Offline change one of the aircraft drones for a tank so it sits on the runway. Enable the dive bombing sight. Map a button to screen capture. Take off with your bombs or rockets and you will see a green cross between your legs when you select your ordinance. Now make runs against your tank. When the green cross tracks up into your gunsight area while diving in, press the screen capture button instead of the ordnance drop button when the cross is on the tank. Review your screen shots to see where to add marks to your current gunsight. Then try hitting the tank offline until you tune the positioning of the dots to your attack style. Your release point will change based on AoA and speed, sort of limiting the marks in your gunsight to being generalized indicators. A rule of thumb from WW2 saw bomb and rocket ladders added to rings below the center pipper every 5Mil.
This link will allow you to read the US NAVY glide bombing manual from WW2. Very good diagrams, tables and explanations for dive bombing. An evening with a Trainer will set you up forever as a Jabo Meister in the game.
