Choose the classification relevant to your car
IMSA identifies GTP, LMP2, GTD PRO and GTD among the championship's classes. Its live timing interface provides both overall position and class position, with gaps to each relevant leader. Start with the class label attached to the car, then read its position in that class.
Do not compare the GTD leader's overall gap to a GTP leader as though it were the GTD title battle. Those cars can have different performance envelopes and race strategies. The overall tower is useful context, but it does not replace the class order.
An original timing-screen example
Imagine car 42 is 18th overall and 1st in GTD. Car 77 is 19th overall and 2nd in GTD, five seconds behind 42. A GTP car passing 42 can change the traffic around it without changing the GTD lead. Car 77 passing 42 for position is a different event: it changes the class contest.
Those are fictional car numbers and positions. The example shows why a commentator can celebrate a class lead while the general tower displays a number far below first. Read class, lap count and gap together rather than only one overall number.
Pit cycles can make the tower provisional in a practical sense
A car that has stopped for fuel may temporarily fall behind a rival that has yet to stop. The current order remains the current order, but it does not alone describe equivalent remaining obligations. Use pit-stop indicators and commentary to understand whether rivals are at similar points in their strategy.
Avoid declaring a net lead from a rough subtraction unless you know the actual stop requirements, caution situation and class rules. Broadcast analysis can explain likely strategy, while the official classification establishes the result after the race and any decisions.
Follow the camera without losing your class
An endurance broadcast moves between several battles. When it returns to your class, recover the car number, current driver, class position and relevant gap. A driver change does not create a different car entry.
If a replay is labelled an event highlight rather than a full race, it may omit much of a class's contest. Decide whether breadth or a continuous record is your goal. This timing explanation uses official IMSA material; it does not establish Canadian access, IPTV Canada inclusion or tested stream performance.

Can 18th overall still be a class winner?
Yes, if the car is first within its own class under the final classification.
Should I compare every car with the overall leader?
For a class battle, use class position and the gap to the relevant class rival.
