How this is worked out
- Both texts are counted the same way, from the same source, with Gutenberg's header and licence footer struck first.
- The gap is stated in words and then in time at 250 words a minute — the rate is printed because a duration without one cannot be checked.
- Difficulty is compared on Flesch–Kincaid grade, which reads sentence and word length only. It cannot see irony or dialect, so treat it as a measure of surface, not of effort.
gap = |230,101 − 229,848| = 253 words 253 ÷ 250 wpm = 1 min of extra reading
