Every drive keeps the measurement configuration it was recorded with, so changing your settings never rewrites past results. The measurement method is documented inside the app. It is not a calibrated measurement instrument. Safety notice: Performance measurements must only be carried out on private, closed or explicitly approved roads or tracks. Secure your phone safely and never operate the app while driving. Use is at your own risk; always comply with applicable laws and safety requirements.
