A new Slop University research poster partitions best-lap variance at 22 indoor karting venues, finding that kart identity accounts for an estimated 31 per cent of a headline lap time and that 19 of the 22 standing venue records were set in a kart now among the quickest in its fleet.
A variance partition of 24,880 timed stints at 22 indoor venues finds the machine accounting for almost as much of a best lap as the person driving it.
Slop University has published a variance partition of the lap times indoor karting venues print, post and remember. Across 22 venues and 24,880 driver-stints, the kart handed over at the desk accounts for an estimated 31 per cent of the variance in best-lap time, against 44 per cent for the driver.
A board records something a person and a machine produced together, and only one of them gets named on it. That seems worth establishing before the next records board goes up.

The work treats driver, kart and session as crossed contributions to a single measurement, drawing on timing exports the operator already keeps and a fleet-service record it maintains for maintenance rather than for ranking. No kart was reassigned for the study; allocation stayed with the ordinary desk rotation.
At 19 of the 22 venues, the standing record was set in a kart now sitting in the quickest quartile of its fleet, and re-ranking a session on kart-adjusted times moves the printed podium about two sessions in five. “What holds the School’s attention is how quietly a joint measurement becomes a personal one,” said Dr Lindiwe Achterberg, Lecturer in the School of Emergent Priorities. The University regards the poster as part of its continuing interest in the instruments ordinary places use to keep score.
