This.
There is never even a 1 second period (much less a 5-7sec period) where NOTHING is going on. When JD40 started coaching me back in 2011, one of the first things he said was "the brakes and throttle are your controls, if you are using one of the controls, you are out of control".
And it is true. Always on either the brakes or gas, always, with no exceptions, ever.
If you think about ANY situation where somebody is coasting, they could have carried the gas further and broke harder (or trailed the brakes in deeper).
If anybody has ever been to Barber Motorsports Park and knows that first high speed chicane in the back section (after the museum corner), It is a high speed (4th gear) chicane that connects 2 straights. I used to get to it, roll out of the gas and coast into it, then change directions and roll back into the gas. After following JD and taking some hints, now I approach that corner at WOT and even when I go past the first left hand part of the chicane, I am still in the gas (where I used to be coasting). Then between the 2 chicanes, I stand the bike up and get on the brakes hard, then trail the brakes into the 2nd part (right hander) to let the geometry change from trail braking help the bike turn, then I pour on the gas, let WOT carry me to the edge of the track and use the curbing on the outside like a berm.
But it you plan on going past that left hand curbing in the gas, you have to plan it way back at the exit of the Museum corner and make sure you are on the proper line to open up the radius.
Because that chicane connects the 2 long straights, how fast you get in and out of it is huge. And by changing my method in that one section, I picked up a full second on my lap times.
