One question. how I select a lap from one session to use it as a reference for another session?

do you know any long video/guide of racechrono to know more about all the options. its quite complex. thanks

There's quite large "+ Add reference lap" button on the session screen. It will add a new reference lap to the lap list.

We do have a getting started guide here: https://racechrono.com/wp-content/uploads/2018/10/RaceChrono-getting-started.pdf

That said we're much better developers than manual writers, so our guideline is that if it needs a manual, maybe it's not good enough ...
