There seems to be a timing bug in Dakar 18 that can occur in Pisco 03 and maybe in other stages as well (time will tell). The bug show it self in the way, that the time that is displayed at the end of the stage (when the onboard shot comes and in the "Stage Completed"-Page) is way off from what it actually should be. In the "Stage-Completed"-Page it states, that there has been a speeding violation and 1 minute has been added. In the second page (Stage Ranking) it doesn't show that penalty time.
Here is an example run where it happened:
For that reason, until further notice, if there is no obvious speeding violation during the run, the time that is displayed on the second page in the Stage Ranking is the time that counts in the Speedrun for that stage.
