Is this mod still needed in 3.4?

Since you can level ships via piracy suppression (piracy must not drop to 0, else it won't work), 500 for veteran is indeed quite low a bar. 100/1000/2500 sounds fair.

Just my personal opinion, but would you consider having the veteran time remain at 1000 and the elite around 2500? Elite units IRL really do have decades of experience, but yeah 10000 is absurd in game.
