Bill Morris, in this and in several previos postings, comes across as a careful and thoughtful observer, and his results should be taken seriously. And I go along with what he says until we get to- "So, my sextant-eye-brain system will give an index error of more than 0.3 minutes away from the best estimate, the mean, one time in twenty. About 45% of the time it will be more than about a minute and a half away from the mean." That first sentence seems highly plausible, but is there some error, by a factor of ten, in the second sentence?
