Of course in that particular scenario the other question (not addressed in the book) is what do base velocity vectors look like.

The RMN DD will open fire as soon as they get bearings on any ship firing on their "shepherded ships", They have a free field of fire, salvo wise until the PN missiles arrive.

Assuming it sticks with the new 'safe' acceleration of 90%, so 702g, then in that 123 seconds a Roland can build a new vector of 846 km/s, and displace 52,041 km. That's wouldn't actually be enough to claw out of the energy range of the Sultan even if the Sultan didn't move either....
All that said, the Roland would be very likely to be able to keep its wedge interposed against a single BC the entire time it was within energy range.
I think we're in base agreement, given that the BC's were apparently lying "doggo" in the rift, which I take to mean in a somewhat stationary position, wedge down, until they launched that first set of missiles. At which point Artemis turns to a divergent course at max accel and the DD goes into defend mode at whatever accel gives the liner the best chance to escape.
If zero velocity in space is the case, the BC has to start building V and can't do it as quickly as the Manticoran ships, making it a matter of time before vector divergence ruins the ambush. Given that it was a mid-range missile duel, I think that would give every maneuvering advantage to the Roland and NONE to the BC at least long enough for 3-4 bigger Mark-16 stacked salvos to likely overwhelm the BC's CM fire and take it out. Yes/no?
I agree the BC is basically 'stationary', so it'll take time to build any useful vector. And as I said, there's no reason the Roland shouldn't be able to interpose its wedge between itself and the BC.
But my calculations above didn't have the BC move at all. They were just showing that if the Roland was unlucky and it's base vector (built over a couple hours of acceleration) was pointed too close to the BC that the Roland couldn't alter that vector
enough before "sliding" past the BC to avoid passing within 100,000 km.
Sure, if the Roland and the BC started stationary
with respect to each other then, yes, there's no way for the BC to ever chase down the Roland. But if the Roland starts out heading towards the BC at 47,966 km/s (0.16c) (as seems to be approximately the case with Hawkwing and Kerebin) that's quite a different scenario.
