Explanation:

Step1: Identify the lowest point on the graph

By observing the graph, the lowest - point on the vertical axis (number of wins) is at 2020 with 18 wins.

Step2: Calculate the decrease in wins for each period

For 2019 - 2020: $26 - 18=8$; for 2020 - 2021: $20 - 18 = 2$; for 2021 - 2022: $22-20 = 2$; for 2022 - 2023: $30 - 22=8$. The greatest decrease is from 2019 to 2020.
