I decided to look at a few more years to see if these results are fairly stable. Here are the results for the matches streamed on the feature table for the last 4 American Straight Pool Championship events. Results are shown in order for 2022, 2021, 2019, 2018, and then for all 4 years combined. The number of matches for the 4 years were 21, 16, 17, and 16, for a total of 70.
