Events

This track has been raced on 3 configurations (Scoring Sidebar, 2.40 mi; 17 Scoring Sidebar, 2.53 mi; 16 Runoffs Scoring Sidebar, 2.26 mi). Laps on different configurations are not comparable, so only events on the 2.40 mile layout are shown; switch above to see the others.

Sectors are not comparable across all of these events. Sector times and the theoretical lap use Runoffs 2016, Ohio Valley Great Lakes Champions 2025, Great Lakes Champions 2026 only. Great Lakes Champions 2024 (different number of sectors) counts towards whole-lap times and trap speed only.

2 laps are left out as timing errors (far too short to be a lap of this track). The rest of those sessions, sectors included, is used.

One row per driver and car (a driver who changed cars has a row for each). Each cell is that driver's best in that car across the selected events, with the session it was set in. Best 5-lap stint is the mean of the driver's quickest five consecutive race laps, and consistency is how far their median race lap sat behind their best in that race (small is a driver who does it every lap); both come from the race with the best stint. The fastest in each column is purple, and a car whose best lap is more than 115% of the fastest in its class is greyed (marked ">115%" beside the driver) and left out of the colour scale. Click a column to sort, a row to highlight it. Theoretical lap is the sum of the best sectors, whichever laps they came from, and never slower than the best lap (where a car's fastest laps were recorded without sector times, its best lap is used). The 115% mark is about the car's best lap only: a car whose best lap is within 115% of the fastest in its class is never marked. Greyed sectors with no theoretical lap mean the sector times on file do not add up to a believable lap. Letters refer to the events above; Q is qualifying, R a race.

Sectors

Sectors are numbered in lap order from start/finish, whatever each event's timing called them; the loop names are SCCA timing's.

Note from the CRB:
When the P1 and P2 classes were inaugurated in 2014, they were intended to occupy
different spheres of competition, with P1 conceived as the premier class promoting advanced
technology and innovation, and P2 envisioned as a lower-cost alternative through restrictions
on chassis materials, engine power, and vehicle aerodynamics, but the contrasting class
philosophies have not translated into the expected difference in lap times. Despite making
various adjustments to specifications over the past five seasons, the front-running P2 cars
remain capable of producing lap times that to most observers are essentially indistinguishable
from the lap times of P1 cars. Accordingly, effective March 1, 2019, additional changes are
being made to the leading P2 platforms to achieve an appropriate lap-time gap between the
P1 and P2 classes, while leaving the specifications of the P2 spec line cars unchanged to
promote more equal competition between the different types of P2 cars. The CRB will continue
to monitor class performance and make further adjustments as necessary.
