You raise a good point with the Catalyst.
I like seeing consistent times on my LapTimer. Within a couple tenths. Normally only happens when I have some clear track.
My PBs have come when I have been chasing cars a couple seconds faster than myself. Just squeezing a little extra on the throttle, braking a fraction later, carrying a little extra corner speed.
What are your settings on the GoPro 9? The quality is really good.
I need to mount a camera inside the cockpit so I can see what I’m doing with my hands. I have a headrest mount and have been looking to get a second GoPro.
