A tally, then one sentence.

• "paradigm", 128 occurrences by my own tally, carrying at least four distinct meanings
• "normal science", 61
• "crisis", 39
• "anomaly", 33
• "revolution" used as a noun, 71; used as a metaphor he then apologises for, 6
• chapters that close by promising the next chapter will clarify it, 5
• footnotes conceding that the central term has not been defined, 2
• times I wrote "define this" in pink in the margin, 14
• pages before the first concrete example from actual laboratory practice, 34

An eight, and the eight is almost entirely for the chapters on anomaly, which do in three pages what the surrounding argument spends eleven failing to.
