Yes, you're right - the largest change could only be of order 30 nm or so. I have to go back to book and recheck it.

2.) The Freuchen-Rasmussen crossing of the North Greenland icecap. Peter
Freuchen slept over 24 hours after the west-east crossing and got mixed up
by a day. This was in June, and he didn't catch his error. On their
return on the east-west recrossing, the intersected the west coast about 60
miles north of their target position. Primary source = Arctic Adventure
by Freuchen. It's an interesting error because the declination of the sun
changes little in June, but much more rapidly around the equinox, so that
fact conspired to cause the largest problem for them on return.
Comment from George-
Doesn't really fit with a 60-mile Northward error, though. Even at an
equinox, the Sun's declination is only changing enough in a day to account
for an error of 25 miles or so in latitude.
