[USER (data scientist)]: Thank you, Tapilot. We aim to examine any significant patterns or shifts in the correlation between court surfaces and player performance in the atp_tennis dataset over time. To achieve this, we will conduct a Time Series Analysis, encompassing line charts, trend analysis, and statistical test results. In light of this, could you please answer my question: Considering the declining trend in player performance on certain courts and the rising trend on others, should tennis associations contemplate increasing the number of tournaments on specific courts or introducing new technologies to improve the quality of certain court surfaces?
