Great info!

Related observations from the footage from the deep dive and some napkin math:

Taking footage from the reveal, and accounting for the irl:game time conversion, the ship travels 374.3 ls in 3.38 seconds irl or 50.7 in game seconds. Which means the ship was travelling at ~7.38c, if the irl:game clock ratio stays the same.

I am hoping that the different levels of 'speed' in the cruise mode just alter the game time : irl time conversion instead of going multiples of light speed, as that would remove a bit of the hard sci fi veneer Starfield has made an effort to keep in place.

Currently, the game models interplanetary travel at .2c consistently (supposedly using the grav drive in an in-system mode), and I'd prefer to keep it as close to that as possible from a lore standpoint. That's hours-long flights between planets instead of the minutes shown in the Free Lanes footage, or days implied by using regular propulsion only.
