The exact number of hyperspace routes in the Milky Way Galaxy was impossible to calculate.
But one thing was certain: the Trade Federation controlled far more hyperspace routes than the Galactic Empire. Even the star maps once held by the Jedi Order had not been all that complete.
If all known routes in the Milky Way Galaxy were counted as 100%, the Trade Federation controlled at least 85% of the hyperspace routes. The Galactic Empire, having inherited the Galactic Republic's database, controlled no more than 50%.
The star maps once held by the Jedi Order contained roughly 70% of the routes. Meanwhile, Count Dooku controlled around 75% on the Confederacy of Independent Systems' side. He had not only obtained data from the Trade Federation, but had also acquired a vast amount of navigational data from the Jedi Order—and had even deleted some of the routes known to the Jedi Order. Naturally, the Galactic Empire had obtained neither set of data.
In fact, this was also an important reason why the Galactic Empire's control over the Outer Rim Territories could hardly compare with the original timeline. The Galactic Empire in the original story had controlled at least 75%, perhaps even more, of the routes after completely destroying the Confederacy of Independent Systems and the Jedi Order.
Although the Duchy of Dawn could currently be considered the master of the Trade Federation, the number of routes the Trade Federation had handed over to Tang Xiao was not large. The Duchy of Dawn controlled roughly 65% of the routes.
In the original story, after the Trade Federation was absorbed by the Galactic Empire, many Neimoidians fled all the way to the Unknown Regions. That alone showed just how abundant the Trade Federation's route data was.
Even the Galactic Republic and the Jedi Order
