So while the 200ms guy may indeed see the 50ms guy's guns out of reach while he already has a gun solution, it's also happens the other way too.
I would go further............ the 200ms guy has had to get used to the fact that he is towing a target on a longer rope
its either at worst 200 + 200 or at best 200 + 50 a ratio of 400:250 (8:5)
the 50ms guy has a target that can be either at best 50+ 50 or at worst 50 + 200 behind him a ratio of 100:250 (2:5)
Hence whilst the 50ms guy is (usually) towing his target on a shorter rope the degree of error as to how long the rope is as a % of its length is much higher for the 50ms guys than experienced by the 200ms guys (they know its long)
In effect the 50ms guy has two faster planes on his six both at 600-800 what he does not know is that one is a 200ms guy who has a kill shot and the other is a 50ms guy who does not. His ability to respond to the situation is slightly compramised thru ignorance.
whilst the 200ms guy who has two faster planes on his six at 600-800 positively knows that both planes almost certainly have kill shots and if one of them is a 200ms guy then he is probably toast already.
