We reached a count of 75,000 words on page 307. Text actually starts on page 3, so that makes 305 pages of text, for an words-per-page average of just about 246. We've copied through page 370, so our latest estimated word count is 370 x 246 words, or 91,020.
Note: That would be more than double the number of words (45,000) that Discover magazine said we could expect from the pencil.
The pencil is harder to measure now, taped up as it is in the Biconderoga (not to mention splinted for stability) but its length is about 1.25"
