Much of the opinion on this thread seemed to depend on geographical boundaries. For example, the difference in temperature between Colby and Connecticut College (13°) compares to that between Dartmouth and Princeton (14°). But the first two are in the same geographical region, so their difference was largely disregarded. However, I doubt a similar subjective interpretation would have been applied to the difference between Dartmouth and Princeton.
The main reason decimals were introduced was because @MWolf seemed to indicate a sincere interest in the difference in temperature between Middlebury and Bates. Those who assumed there’d be no math could have skipped the post, of course.
The daily high temperature commonly occurs closer to solar noon than to sunset.
