the.com/track record

means A person's or organization's history of past performance, used as evidence of what they're likely to do next.

from Literal before it was figurative: a 'track' is the oval course where racehorses or runners compete, and their 'record' was the documented times and results posted on that track. A horse's track record told bettors exactly how fast it had run before — the best predictor available of how it would run again. By the mid-1900s the phrase galloped off the racetrack and into business and everyday speech, keeping its core logic intact: past performance, formally logged, as the evidence you're judged by.
