When sailing, there are a few techniques to increase speed by trimming the mainsail according to the wind and wind pressure.
Likewise, perhaps the MA has improved the dynamics of the Warshawski Sail and made it more efficient. Or, rather, in the case of the Selker Shear, safer or manageable.
In addition, I was thinking the streak drive may actually enable the ship to interact with a wave in a totally different manner. For example, instead of bouncing off a wave, can ride the outside of a wave.
Sails can already accelerate hard enough to overwhelm the inertial compensator and turn all the occupants to mush. What you'd need to, somehow, improve is the depth of the "inertial sump" which doesn't sound like it is influenced by any aspect of the sail -- that seems to be an effect of the inertial compensator. When the RMN got better acceleration it wasn't because of breakthroughs in sail or wedge design; it was (Grayson inspired) breakthroughs in compensator design that allowed deeper sumps and/or more efficient use of the sumps by the compensator.
Here's what RFC says about sail acceleration
More Than Honor: The Universe of Honor Harrington wrote:The natural grav waves of hyper-space, with their incomparably greater power, offered a much "deeper" sump than the artificial stress bands of the impeller drive, which meant that a Warshawski Sail ship could deflect vastly more g force from its passengers than one under impeller drive. In general terms, the compensator permitted humans to endure acceleration rates approaching 550 g under impeller drive and 4-5,000 g under sail, which allows hyperships to make up "bleed-off" velocity very quickly after translation. These numbers are for military compensators, which tend to be more massive, more energy and maintenance intensive, and much more expensive than those used in most merchant construction.
(And hopefully those MAlign ships are packing an inertial compensator despite being unable to use it under spider drive -- else their acceleration limit even in a wave will remain the 150g or so their crew can sustain long term (somewhat higher if they're willing to be subject to 2 or 3g on a long term basis)
But frankly improving sail acceleration is a really marginal benefit. Ships almost never fight in a grav wave, so tactical acceleration is basically moot. And strategically it just doesn't take much difference because you already reach your top speed so quickly. Doubling your acceleration (from the 5000g in the quote) would drop your total trip time by, just under 31 minutes. Instead of taking 61.2 minutes to hit top speed (0.6c) it now takes 30.6 minutes. Doesn't mater how long the trip is; you save about half an hour.
In contrast, the streak drive, by allowing you to climb two hyper bands further, will cut the trip time by 31% - which is going to save you vastly more than a half hour on any real trip.
You recently said something similar about how you thought the streak drive might affect how ships interact with grav waves. I forget which poster reminded you that because the streak drive is only an improved hyper generator that this simply can not be the case.
Hyper generators have no affect on how a ship moves once it is within a given hyper band; they only allow it to cross hyper walls between bands.
"Streak drive" is just a slightly deceptive cover name, like the US calling it's WWII air dropped anti-submarine acoustic homing torpedo the Mark 24 mine. Hopefully mislead any unauthorized person who overhears or comes across a passing reference to it -- in a way they wouldn't if you called it the streak hyper generator (plus that's just an awkward mouthful to say every time)
