'''Delayed lap counts''', or '''DLCs''', are a [[checkpoint]] exploit in ''[[Mario Kart Wii]]''. They are not allowed in the [[Category rules | no glitch category]].

== Overview ==
Under normal circumstances, laps are started by crossing from the front of the last CP to the back of KCP 0. A delayed lap count consists in starting a lap by entering KCP 0 from the front or sides instead. In general, performing a DLC involves breaking the checkpoint system by exiting a checkpoint in the last KCP region from the side, so that KCP 0 remains active, then driving into KCP 0 from another side. DLCs are mostly used in flap categories as part of a lengthy lap setup, to start the lap facing backwards in preparation of an [[ultra]] or to trigger the lap count with a headstart; on the other hand, they are rarely useful in 3lap categories.

To perform a DLC, all the usual requirements for getting a lap count must be satisfied. The condition on the KCP value is naturally satisfied. If starting from the last CP of the track, performing a DLC guarantees a lap count. Otherwise, starting elsewhere from the last KCP region and performing a DLC will only count the lap if the [[Checkpoint#Lap%, Race% | Lap%]] value decreases by over 0.95 upon entering KCP 0.

The lap split calculation bugs out when starting a lap with a DLC. To determine the exact duration of a lap with float-level precision, the game makes a calculation using the position of the vehicle on the frame before and after crossing into KCP 0. However, this calculation assumes that KCP 0 is entered from the back; entering it from a different direction causes the lap split to always be equal to (length in frames * 60000/1001 + 1) ms, meaning lap splits are only calculated up to the precision of one frame.
