Four-Actor tennis research workflow links match cohorts to point-by-point data

A tutorial describes a staged workflow for tennis analysis that starts with a broad match cohort and narrows to detailed point-level investigation only when needed. It uses four data tools in sequence, with a match identifier serving as the handoff between stages rather than fuzzy matching on names and dates. The author, who maintains the tools, reports saved results from October 23, 2026, covering 233 matches (106 ATP, 127 WTA). A separate point-stream export joins to 116 of those matches, or 49.8% of the cohort, which reflects overlap between two exports rather than the source's full coverage. The piece cautions that statistics computed on the joined subset should not be presented as findings about all 233 matches.
