In addition to showing my current/last/best lap times. I would also like to see my theoretical best lap time. The theoretical best lap time is the sum of the best time through each sector of the lap within the session.
Example:
Sector 1 best: 30s (Lap 1)
Sector 2 best: 28s (Lap 4)
Sector 3 best: 35s (Lap 2)
Theorectical best lap = 30 + 28 + 35 = 93 = 1:33.000
This information is useful for the driver to determine how close their best lap is to their theoretical best. As an example: if the difference is seconds, I’m going to keep lapping and try to put together a more consistent lap; if the difference is milliseconds, I might decide to make some tuning adjustments or upgrades, or take a break for a bit and try again later.
