Found the acceleration bit... they broke orbit from Nuncio and then sat in space with 0 relative velocity, letting the planet move away from them for 5 hours.

Five hours in which Pontifex had moved over half a million kilometers, taking Hexapuma with it. If the bogeys had managed to put one over on Hexapuma and get a recon drone into space headed to intercept the planet at the time they themselves would approach the hyper limit, its course would take it far enough from Wolverine's present position to make anything as weak as a LAC's impeller signature invisible to them. And since Bogey One and Two themselves were still far beyond shipboard detection range of the planet—
"Stand by for acceleration in three minutes," Captain Einarsson's voice said in her earbug.
The three minutes ticked past into eternity, and then the six LACs and their pinnace parasites went instantly to five hundred gravities of acceleration.
They waited 5 hours to get away from RD's, accelerated by using the Nuncian LACs 500g acceleration on course to intercept the freighter, and then dropped the wedges entirely. And technically the Nuncian LACs were only going along as a backup plan, as per later

As you'll see, Sir, she's a spinal design, and I've highlighted her hyper generator room's location. According to her emissions, her generator is off-line, and it looks like only her beta nodes are live at standby levels."

The small force of Nuncian vessels and their Manticoran parasites were moving towards the freighter at a relative velocity of just a hair over 17,650 KPS, and the LACs' maximum deceleration rate was five hundred gravities. It had taken them an hour of steady acceleration to reach their current velocity before shutting down their wedges to avoid detection, and it would take them another hour to kill their velocity, during which time they would cover another 31,771,000-plus kilometers. At the moment, they were about forty-two million klicks from the freighter, so to decelerate for a zero/zero intercept, they'd have to begin decelerating in no more than four minutes. The pinnaces, with their higher acceleration rate, had a bit more time to play with—they could achieve a zero/zero intercept if they began decelerating any time in the next fifteen minutes. If they didn't begin decelerating, they'd blow past Bogey Three at a range of about 67,500 kilometers and a velocity of over seventeen thousand KPS, in a shade over forty minutes.
But the instant any of them began decelerating, even a half-blind freighter with civilian-grade sensors was bound to spot them, and they would still be far out of energy weapon range. The small lasers mounted by Hexapuma's pinnaces, without the more powerful gravitic lensing of their mothership's main battery weapons, would do well to inflict damage at any range over eighty thousand kilometers. The Nuncian LACs' lasers, although bigger, with more brute power, had far poorer fire control. They had the range to hit the freighter from a half million kilometers, but they'd have no effective control of where they hit it, and the sheer power of their weapons made any hit far more likely to inflict damage which might prove lethal instead of merely crippling.
So they'd have to overfly the freighter, disable her hyper generator in passing with the pinnaces' lasers, and then decelerate and come back. The fact that the Dromedaries were a spinal design would help—Abigail had been afraid they'd have to penetrate deeply into their target's hull to reach her generator, and Captain Terekhov had been forced to face the same possibility. That was the real reason Wolverine and the other LACs were along, because in the end, Terekhov was willing to risk destroying the freighter if that was the only way to stop it, and the Nuncian weapons were powerful enough to blast through to a deeply buried target.
They couldn't be sure the pinnaces alone could handle the freighter, whether due to hot nodes or the wrong design, so the LACs were part of it for a contingency scenario, and their slower acceleration curve made the case for how quick they could accelerate to sneak in ballistic, and whether or not you have to use their larger but less accurate guns, or hold out for the pinnaces to pull a (somewhat) precision strike.
