That actually makes a lot of sense and explains some of the stuff I noticed in the game. Flying earlier ships that are light, even with limited acceleration you tend to get to top cruise fairly quickly... but once you're in something big with a lot of mass it takes a loooong time to reach your top end.

That makes me think of another question, though: does the ship mass contribute directly to any sort of handling, or is it only used for things like collisions/ramming? I always assumed that it at least offset acceleration, since the default ship hulls at the large end all seem to have negatives to max speed and maneuver but nothing for -acceleration.
Also, let me summarize here before I change anything for public consumption, just to make sure I have everything right!

Does this look correct?
Maximum normal speed forward is speed_max.

Maximum normal speed in reverse is speed_max * reverse modifier (default 0.6)
Acceleration toward maximum speed is dictated by Acceleration.
Turning ability per second is determined by Maneuver
Cruising maximum speed is speed_max * cruising modifier (which begins at 2.0)
Cruising acceleration is acceleration * 0.33 (roughly).
Strafing max speed is speed_max * strafing modifier (default 0.4)
Strafing acceleration is the same as acceleration.
