What is logged is not necessarily what happened and it appears no one but Tesla has this data. What events register changes to the pedal setting? is it purely a measure of the pedal movement or what the system decides the setting to be, meaning can other systems in the car affect the value?

without unfettered access to the full data that Tesla has we will never know. Unlike Toyota Tesla does not seem willing to cooperate.

I am all for logging and accessibility to it but logging is only as valuable when you know the how and why of each event.
