I agree that they needed to conserve for... Honor knows what in the future, it just seemed a bit of shaky logic to use whatever they did to get partway, then walk the rest, when it would have literally only taken a few seconds more falling to get the rest of the way there. I mean, it's not like they had one of Navani's wrist clocks to judge the flight time within seconds anyway, lol. Had they just flown for a while, then decided to walk to save Stormlight, that would be more reasonable, but they actually planned to walk partway before leaving the ship!
Oh well, not a big deal in the long run, of course. Just caught my attention when I was thinking about how fast they'd accelerate when fall-flying!
Narativium indeed. Certainly the most important and powerful force in the Cosmere. =)
