Looks like you skillfully countered the spin to the right and saved the car from the wall, but then didn't counter a second time to straighten the car from continuing to rotate counter clockwise? (which worked out fine b/c all the energy got dissipated in spinning on-track).
Since it sounds like you are open to trying new ideas(
)...
Why not try turning earlier and a bit less for 3, which will set you up to work less for the turn-in for 4. From the video, my guess is that you needed to tap the brake for 4 in order to the get the front to bite and get the car to turn-in.
Thanks for sharing.
