This week we continue chasing the clock and it is now time to unveil the mystery that appeared in our previous post. Following the Time VS Time graph we discovered that our driver did some magic in the second sector gaining a lot of advantage in his second best lap.
Let’s examine the Speed graph and find out if it’ll help us determine what happened. What the blue line is showing you is that the driver is keeping higher speed through turn 6, resulting in higher speed before turn 7. A later turn-in for turn 7 on the other side allows earlier acceleration and thus – higher speed in the next section despite the little lower apex speed.
How do we know about the later turn-in? Well, RaceCloud is automatically detecting the braking and turn-in points and displaying them for easier and faster analysis. According the World Champion Mikko Laine, that’s the best feature that we have created so far and he also says that “It’s really useful for all the drivers including rookies and pros“.
If you take a closer look at this section and the points over the racing line you’ll see that in the “blue” lap the driver initiated the braking and started turning at one and the same point, while on the other lap the points are different and the turn-in is earlier. A turn-in point in the middle of turn 5 in the red lap on the other side suggests a possible reason for the lower speed through turn 6, mentioned above. The later braking and more inside racing line caused the driver to work harder and struggle for grip and speed into the next turn and all this resulted in time and speed loss through the whole next section which is faster and thus more important for taking advantage.
In the final section of the track, the “red” lap is “back in the game” carrying more speed into turns 15 and 16 and that helps it to finally make it with a negligible advantage of 0.03 sec. But what caused the loss of 2 tenths of a second in just a few turns? Keep following us so we can find the secret together, next time on RaceCloud Blog.
