This plugin shows your projected run time on multilap tracks given your performance on this run. The plugin can show the projected run time either at the start of every lap or at every checkpoint. The behavior is as follows:

Lap 1 - Nothing is shown

Lap 2 Trigger - Project time is lap 1 time * number of laps

Lap 2 Checkpoints - Current time + lap one time from this checkpoint + lap 1 time * number of laps left

Lap n Trigger - Current time + average lap time (not including first lap) * number of laps left

Lap n checkpoints - Current time + average time finish lap from this checkpoint (not including lap 1) + average lap time (not including lap 1) * laps left

Configuration

This plugin has a few tweakable settings:

Whether to show the prediction every checkpoint or only at the beginning of a lap.

Change size or position using settings.

Toggle to show

Limitations

The plugin works better on tracks with more laps. Maps with only 2 or 3 laps will be pretty inaccurate.
