Minimum corner speed

Every corner has a moment where the car stops slowing and starts accelerating. The speed at that moment is the minimum corner speed. It shows how much speed you carried into and through the bend, and where it happened tells you something about your line.

Raising minimum speed by a couple of mph in a long corner is often worth more than braking later, because that extra speed lasts for the whole middle and exit. Comparing min speed between laps is one of the clearest ways to see whether a different entry worked.

But higher is not always better. Over-slowing is a common novice habit, but over-speeding into the apex is a common intermediate one: min speed goes up, the car runs wide, and exit speed drops. Always pair min speed with exit speed or the time for the following straight.
