Hello, I have too much time and I did some calculations from the lap times at FIA's site.

I calculated the average lap time excluding the laps affected by pit stops and the standard deviation for those laps. Pitloss is the difference between the laps affected by pitstops and the average lap time summed together.

Luca was slow, but improved immensly throughout.

Interesting stats, would be good to compare over several races

Ps. if you use code tags you'll get better formatting -

Aug 26 2009, 12:25

comparing laptimes for a driver running in clean run to a driver running third in a 5 car train is meaningless
as is comparing laptimes for a driver on the lead lap to a driver that has to move over and get lapped every 3 corners ;)

Great stats, thanks for doing the leg work.

Amazing debut for Grosjean to compare so favourably to Alonso. Especially considering he started much further back. Proves how BADoer was.

Nice work.
It would have been much more thrilling and exciting had Lewis' second pit stop been quicker.

Now the stint times with standard deviation, gets more interesting. EDIT: Added stint lengths, excluded the laps affected by normal pitstops.

Probably an effect of his one-stop schema. He seemed to drive a very good race actually, considering his strategy. Tyres didn't seem to like that and the fuel effect seemed rather large, but my impression is that he was consistent, but too slow with full fuel and not getting down to really fast times with worn tyres.

the only stat I see fisi being "fast" is pit loss, which is obviously because he stopped fewer times than the others (pitloss seems to be cumulative)

What about Glock? From nowhere to the top of the stats.

So Hamilton spent 9s more in pit than Rubens, how far after was he taking checker flag?
Lost the race in pit...despite Mac team saying no?

I was looking at the stint times with standard deviation.
His 2nd and 3rd stints were very fast, if I understood the stats correctly.

Not a one lap only, whole the last stint he was blody fast, but he was on newer tyres than others at the same time as he pitted really late, but at Hungary he was also very quick during the race, it's that they don't get the full potential out of the TF109 on qualifying

Aug 26 2009, 19:35

He ran low-fuel too, he 3 stopped.

In Hungary he wasn't rate quick, but he was tanked and kept a reasonable pace up to pass a load who were stopping more than him.

We have to be carefull with the use of standard deviation, if a driver is loosing or winning constantly time, his stdev will be around 0. But his laptimes are not constant.

Tenmantaylor

Aug 26 2009, 23:10

The 10 fastest lap average is a useful stat providing you know pit strategy, can only compare people fairly on the same. Its also really good for checking consistency. The worse your 10 best average vs your finish pos shows how consistent you were. Kova vs Button is a good example of this. Button proved his pace was amazing at his best but drove a poor race. Kova was quite slow ultimately but his excellent qual and consistency bagged him a good race result.

I'm afraid that's incorrect. If he is loosing/gaining constantly he will have the same sd as a driver that randomly drives between the two extremes of the constantly gaining/loosing one.

QUOTE (Tenmantaylor @ Aug 27 2009, 00:10)

The 10 fastest lap average is a useful stat

Best measure of a driver's speed is x number of successive fast laps, I think. The question of x is empirical. Ten is a round number, but x may well be the number of consecutive free laps (not hindered by another driver) the driver had, and so we might want to adjust the x value accordingly.

For reliability of driving fast, I think the best measure would not be a statistical value at all, but a graph.
