Ahhh!!! I see how you're reading it, and yeah - I think the mistake is much more on them than you. The parenthesis are not describing the value before them, but indicating what is IN the parenthesis! I'm the sort that ignores infographics and goes straight to the text, and it's much clearer there. Check out the report highlights:
---
The all accident rate was 0.80 per million sectors in 2023 (one accident for every 1.26 million flights), an improvement from 1.30 in 2022 and the lowest rate in over a decade. This rate outperformed the five-year (2019-2023) rolling average of 1.19 (an average one accident for every 880,293 flights).
---
So in the table their "All accident rate (accidents per one million flights)" row is giving you two different pieces of the data. The first is accident rate (which is per million sectors) and then in the parenthesis is the accidents per million flights. And actually even that's wrong, since they actually give you flights per accident -- whoever put that table together clearly was not big on the whole accuracy thing.
So when you see "1.19 (1 accident every 0.88 million flights)" that means the rate per million sectors is 1.19, and the rate per million flights is 1/0.88 = 1.14.
