Tangential and very late to the thread, but, In the racing/track world, any time spent off the accelrator or brake is literally leaving time on the table. The idea being; you are going at 10/10 until the exact point you know you need to go 4/10 at an apex and apply full braking. Then getting right back up to 10/10. Similarly, I notice that i do a lot of this "sine wave" driving (IE , gas, brake, gas brake) when I'm heavily loaded with passengers or on a curvy road where I don't quite know the ratios. So I'm often not expecting to need to brake so heavily but, for safeety of course, need to.
