So the manga is already handling some things much better than the WN, as far as I can tell.
My biggest gripe isn't that Krishna is being overhauled, it's the fact it's being overhauled (and the reason given here is 10 times better than the reason given in the WN) by the company that has done its all to make as bad and unprofessional of an impression as possible. And it's shown so much desperation that I feel like this is a company lagging behind in capability with lackluster engineers. Why, in all of space, would I want to trust this company?
The decision to go with them makes Hiro, Elma and especially Mei feel out of character. Especially giving flight data of Krishna for the following reason:
That data is useless for anyone who isn't fighting against the ship.
1) The manufacturer, assuming they can replicate the ship, can test it themselves once they build it, and can use remote control to test the absolute limits. They'd need to, anyway, considering their manufacturing might be better or worse than the original.
2) They need many different pilots and test pilots to create a generalized enough flight computer system for use by many customers. Hiro's data wouldn't even be important for the sake of this, and could be harmful considering most people aren't as skilled as him, and optimizing for the best of the best can get regular pilots killed.
3) It can thus only be sold if its going to be worth the discount they're getting. But who would buy it? Oh, right, anyone who wants to take out the Krishna. And pretty much only them.
There's something else that happens in the near future that only makes this business deal even worse to anyone with 2 brain cells to rub together.
But this is the worst arc in the WN, and things get better after it, so I encourage anyone to stay for the ride and get into the next arc before you decide whether to stop reading or keep going.
