Update:
| Week | On chapter | Behind | Actively reading (sum) | Delta |
|---|---|---|---|---|
| 1 | 46 | - | 46 | - |
| 2 | 27 | 4 | 31 | - 15 |
| 3 | 25 | 5 | 30 | -1 |
| 4 | 22 | 8 | 30 | +0 |
| 5 | 20 | 7 | 27 | -3 |
| 6 | 17 | 4 | 21 | -6 |
So, the week of break seems to have equally impacted the reading along and the “behind” categories.
I wonder if there’s a procrastination effect (even if you are late, the extra time makes you slow down even more and eventually drop) while some people who were actually reading along just forgot about the book and went on to read other things.
Still not statistically significant, but I’ve never seen a break increasing the number of people reading along so far.
That could be something to try next time: instead of taking a break, slow down (eg split the next week over two weeks). That would be the same average number of page per week, but without interruption.
