Black to Mount Drift.  It seemed to me he marched nearly 900 miles in 3
days, which is ludicrous. ...

#> During those 7 days, he marched in the vicinity of 800 miles, which works

#At <http://www.vhtrc.org/mmt/2003/hunter-report.htm> you'll find
#a woman's course record for a 101.7-mile race: 24 hours 40 minutes.
#She wouldn't have done it again the following day.  A march of 800
#miles in 7 days is better than 3 days, but still impossible (unless
#the Jenoine modified human endurance, or a Dragaeran mile isn't an
#American mile, or something).

I can't speak for Steve, but I can quote him.

How High are Shortisle's File Cabinets?

Spying magically on Shortisle's records room before entering it, Kiera
observes: "If the ceiling was as high as the ceiling of this room, then
the filing cabinets were about eight meters tall..." [Orc164]. That's
about 25 feet. Even Dragaerans would need ladders to get into most of
the drawers. Eight feet, on the other hand, would be a reasonable height
for filing cabinets for Dragaerans. There's no suggestion of ladders
when Kiera finally enters the room and snoops through all the cabinets.

[...] You are also right about "8 meters" being "8 feet." I had
forgotten, when I first wrote it, that I wanted Kiera thinking in meters
to represent a different one of the too many measurement systems in use
in the Empire, and then I somehow forgot to convert it, but just changed
the word. Ooops.

How High Is Bengloarafurd?

Bengloarafurd had "a population of eleven thousands, more than twice its
elevation measured in meters" [TPG250]. Round that down and say 5,000
meters, or 5 kilometers, or slightly over 3 miles. Castle Redface is
even higher [TPG277]. Sea-level athletes notice a real difference in
Denver, "the mile-high city". Yet our heroes don't seem to notice any
shortness of breath in either Bengloarafurd or Castle Redface. (Pointed
out by Ben-San Arizona.)

Well, they are heroes, and in excellent physical condition, and they've
come up gradually and had time to become acclimated to the change; and
if Dragaera City is at a significant elevation, there's less change than
if they were coming from Adrilankha, at sea level. Besides, maybe
Dragaerans are less sensitive to the difference than Easterners are.

For that matter, how big is the planet that Dragaera is on? We can
suppose that its surface gravity is about the same as Earth's, but
(leaving aside any magical effects) if it is less dense -- and our own
planet appears to be the densest in our solar system -- then the gravity
gradient would be shallower, and air pressure would fall off more slowly
with increasing elevation, with a correspondingly slighter physiological
effect.

On the other hand, how much simpler to assume that Brust (author or
translator) had the same problem here as with the file cabinets,
referring to meters but using the measurement in feet. Then the
elevation is just about a mile (5,280 feet), the same as Denver, which
alleviates the problem to the point of insignificance.

	---------------

Of course, if you throw in assumptions like that all over, you can solve
many geographical conundrums, but you also lose most of the constraints
that give the problem a point and make it fun.
