that only works because the 2 BS are exactly 100km away from the 3rd one. Stop claiming that it works in every mission just because it can work in one mission. THAT is stupid.
Just because you need one MJD to reposition yourself in this misison, or in the other one with 6 Bs that spawn exactly 100km from you, does not allow you to say you only need 10s to reposition. That is just a lie.
