@Ultrasonic_77which begs the question, why are different people getting different results?
One key difference is that @BadMayh3m used a controller whilst Marcel Kiefer was using a wheel and pedals. Beyond that @Ialyrn largely covered the limitation of anyone trying to test this I think - the more somebody is able to drive optimally without assists the more likely they are to notice a detriment from not doing so. I drive without TC but I wouldn't be remotely surprised if I'd be faster with it. My reason to drive without assists, or using cockpit cam, is not because I think it's faster though.
Edit: Marcel's video did also highlight how hard it is to test this reliably due to normal variation between laps anyway.
