Because these are not official sector times, they won’t be 100% accurate. Each sector has an accuracy of up to 0.03 seconds, which is very minimal. Based on a typical 45-second lap, this means the sector times are roughly 99.8% accurate
Accuracy can be affected by factors such as:
Different camera frame rates , Varying points of view (POVs), The transponder position (as it's at the back of the kart)
Despite this small limitation, Sector Times provide a highly useful guide to track performance, identify strengths and weaknesses, and improve lap times.
