In the benchmark's git log sample, the script uses split(" ")[4] assuming the fifth word on each line is the commit type, but this only holds when the author's name is two words; the tester ran the same script on context-mode's own commit history (2,234 commits, 203 KB), and the summary output went from 107 bytes to 7,071 bytes, a 96.5% savings, but the output wrongly showed the most common type as 'update', when in fact 550 commits came from the single-word author name github-actions[bot].
