There's some truth there. That's getting between the devil and the deep blue sea. Always beware of the allure of highest speed when seeking to retain speed. When road racing, highest speed through and out of the turns usually equals best lap times. In some tighter track corners, and most autocrosses, retaining speed is good, but cutting distance reduces lap time. Figuring out and managing the balance of those two (retaining speed, and reducing distance) in real time is a learning curve for sure!
