I don't think it should matter in these cases, but we/you have to be aware of it when reading the data and something is screwy.....
Good thinking, thanks for the reminder.

IIRC duration is a factor in the car's programming, mayybe allowing a couple seconds of simultaneous input. Note that we can still blip the throttle even with mega-pressure on the brakes. Also, I have an extra-wide throttle pedal on my car, and when other guys have auto-Xd it, they frequently hit the gas when braking, and the car allows a good bit of it, even with the clutch out.

I'll keep it in mind when I look at some test data, see if I can figure out how it handles the situation.
