There in the image it jumps from 9 to 13 (and there is 9 and 13 in the same row, just like 14 and 16, meaning the 15 is skipped as well). Maybe there's something I am not understanding?
Viewing post in Day 4 Encounters Table problem
Oh I see the confusion, and it’s probably caused by the way the column has been squashed. Those rows are for results between 9-13 and results between 14-16. They don’t have individual rows for each number; those ranges use the same encounter as a way to modify the encounter frequencies. It’s the same for 17-18; there’s not a blank row after 18, you use the same encounter as if you’d rolled 17.
