Thoughts on MPT Sprint 2007 Rd 2

So the timings for this past Sunday's event has been released.

Descriptive statistics:

Confidence Level (95.0%)0.250174034

It is human nature to always look at the outliers. True, at the end of the day, people don't remember who came in 3rd. However, we also have to consider that the cars we fielded are daily drivers. No shop cars. No sequential gearbox or dog boxes. Air-conditioning and heavy glass windows still intact and working. No carbon fiber doors. No drag slicks or treated tires. Hell, one of the drivers even showed up in Yokohama AD07s!

Look at the positive skewness: this means there's more data in the right tail than would be expected in a normal distribution. Make no mistake about it: the competition is tough!

Yet given these difficult circumstances, we managed to prevail against the odds.

The best performer is in the 64th percentile (i.e. it was quicker than 64% of the cars that took part in this event) and 2nd best, in the 59th percentile, with the 3rd car just above average. Not bad considering it was running on a stock Evo 9 titanium turbo and pump gas!

Hopefully we can further improve upon the results in the next round.
