Here are the throttle traces for both drivers with the speed trace just like you can see in the video above. The corner is the fast left hander turn one at Whilton which leads into turn two.

The green line shows the throttle position for Lead Foot, and the red is for Twinkle Toes. The difference is clear, the green trace is on full throttle much longer than the red, then lifts heavily before slamming back on the throttle. Meanwhile the Twinkle Toes is already off to 80% throttle and hovers between 40% and 80% before climbing less drastically back up to 100%.

Now, with just the throttle trace, if you told me that the green driver was quicker than the red I'd buy it. Logic says that he is lifting later, and getting back on earlier. Also visually both drivers looked smooth and there wasn't any excessive sliding. So surely green is quicker????? Nope, he's losing over 4 tenths which he doesnt recover up the following straight.

Despite being off the throttle early, the red line of Twinkle Toes is carrying more speed into the corner, carrying more speed through the corner and onto the straight.

I won't fully explain the reasoning why Twinkle Toes is so much quicker, but its enough to say that if you are progressive with your throttle rather than lead footed, you will be quicker, especially on high speed corners. And also, next time someone tells you that the earlier you get hard on the throttle the better, you can say that isnt always true!
