Using Race-Keeper Software to Analyze Corner

In addition to EAE (Entry, Apex, Exit) speed comparisons for each lap, lift and braking points can be easily analyzed with speed graphs provided.  Note the end of acceleration as the speed line begins to decline (lift point) and then note when the downward slope of the declining line increases (brake application point). There is almost 80 feet difference when the car is "coasting".  Faster lap times result from the reduction in coasting time before the application of brakes.

See Graph above.

In addition, the driver was sure he was "hard on the gas" approaching the apex but facts show otherwise (See Graph below).  End of braking and light throttle applied as car approaches apex, but car is not really accelerating for 100+ feet until apex when driver does apply full throttle. (Slope of upward line increases.)  Reducing/eliminating these "unproductive" times can optimize lap times.  At 80 mph, car travels 117 feet in one second. Just during Turn One here it is seen that nearly two seconds are spent coasting.  Significant improvement is possible.  (10% improvement in a 2 second "segment" reduces lap time by 0.2 seconds. Do this in five corners and you can see a full one second drop in lap times!)

 

 

System also provides instantaneous G force acceleration (in line and sideways) showing the extent of throttle application.
