As @Assimilator said, that was always only one or two quarters in a row (Q2-Q3 2015, Q4 2018, not 2019, Q4 2020) and then since Q3 2022 the last seven quarters in a row.2015: 18%
2019: 18.8%
2020H2: 18%
2022: 10%
2023Q4: 19%
What is it with that random line that isn't even a real line? Did you just fail at drawing a straight line from the first to thal last shown quarter or did you connect random quarters on purose?
