Just for Graphs

For the masochists amongst our readers, here is a way of reporting a race we used last year which, except for Tristan Cliffe, was met with unrestrained apathy by our readers. But as an accountant I believe there is no substitute for ruthlessly crushing the very life and soul out of a subject by reducing it to bare numbers and better still graphs. I've even booked tickets for an entertatinment about Excel. , so much do I love it. So here goes with the race.

Phew, that was exciting wasn't it. For the odd person who doesn't find the graph obvious, let me explain. Lap numbers are on the horizontal axis, time on the vertical. The blue line at the bottom is F3 winner Zachary Claman de Milo. The variation in it shows how he has cumulatively varied from his average lap time, so it is positive for the first lap, and gradually moves down to zero. The up-slope in the 8th lap mean Zachary had a slow lap (by his standards) on lap 8 but the following steep downslope shows he made up for it on lap 9. Similarly, Stuart Wilthsire's nightmare is shown by the orange line - he lost 2 laps at the start. Daniel Tapinos started well but had a disaster on lap 7, thereafter fighting with Robbie Watts until pulling out a lead in the closing laps.

The graph also shows relative performance - the steeper the line, the more the difference from the winner's average lap time. Where lines are close together, the racing was close. The vertical scale is (roughly) winner's lap time (1.22), so where the 1.22 line crosses is where lapping took place, similarly the 2.44 is the second lapping.

The graph could be used to analyse a driver's own performance by making him the "key" driver like Zachary, then there would be lines above and below the horizontal axis and a wider gap on the vertical axis as a slower car would have a greater lap time.


Robbie Watts initially got away from Daryl Jones but the latter kept him in his sights, getting closer over the last 3 laps until he pounced, winning by a Usain Bolt in Beijing margin. David Gillett and Neil Harrison were another closely matched pair, David just drawing away at the end. Behind them, Tony Bishop broke away from a fighting pack on lap leaving James Rimmer to just edge out Shane Kelly, both of whom escaped from Richard Purcell. While Russ Giles and Mike Hatton were also very close. John Whitbourn (DTec) and Matt Walters (1800) were another nose to tail pair, the lead going to John.

And because you can't have too many graphs, here's just the 2000s. Note how it shows how close 6 cars were on laps 4 and 5. It shows one or two other things but I don't want to get punched if I show my face in the paddock.
