What is the maximum time with path recording ?

This article talk about the copilot function : path recording. 

Knowledge

There is no actual limit to the length or duration of the path you want to record. The only limit would be the available memory to store your program in.

Also, if you record a long path, the inconvenience is the time taken by your program to start running. The longer your path is, the longer time it takes before your program actually runs when you click the start button. It is easier to work with smaller paths because it is much simpler to correct an error.
