"Bird" distance markers look incorrect

[some1]

In DCS the distance markers presented on the gunsight are  weirdly spaced. They are at 2000m, 1200m, and 300m respectively. Which makes it quite hard to estimate distance to target.

2000 meters is way to far for effective gunnery. Even MiG-29 real manual gives 1200 meters max for accurate gun aiming and 800 meters effective gun range. Doubt the older system would fare much better.

The marker at 300 meters is useless, it's the same distance you get "breakaway" red lamp next to the gunsight, so it's redundant information.

 

On a real footage you can see the markers were evenly spaced, so it was possible to read the distance like on a scale.

And here is an interesting interview with technician, who worked on Polish Mig-17s equipped with RP-5 radars. He says the 3rd marker was at 400m and the max effective range was 800 meters.

So unless Razbam has better source that clearly states that currently implemented markers are correct, they should probably be placed at 400-600-800 meters respectively. Or 400-800-1200 meters if you believe MiG-19 would be set up for longer gunnery range than MiG-17.
