What are the Data Sources?
Either the FIA WEC or IMSA Official Timing. Other sources will be credited in post.
The FIA WEC timing site contains the BoP data used here, IMSA keep it on their technical bulletin pages.
How do the charts work?
I hope these are self explanatory. I try to match colors of classes, and to a less extent cars. Key moments are noted on charts in some cases.
I plan to add full descriptions to typical charts.
In the meantime I’ll quickly mention a common chart and table. There is a chart that shows lap times in order of fasters to slowest. Not only does this give a great indication of whether a car just did a few fast laps or is consistent, it also allows the user to get an idea of how many fast laps can be considered when averaging.
The average Top x fastest laps is a nice simple way of seeing if a car or driver is consistent. How many laps are included changes based on how long a race is, how many laps were effected by cautions or weather.
If only one of each manufacturer is included it tends to be the one that is consistently fastest, or one of key interest.
Ha! I’ve found a mistake!
If you notice something that is wrong or looks odd, please comment to let me know.
The lap counts are different
On the average lap time tables only laps that were completed are counted. On the charts that show how much running was completed you only need to have started the lap (registered the first sector).
There was no particular reason for this, although if I was to make one up now it would be that the chart showing how many laps were done in testing or practice a lap that you don’t complete can be very useful for you. Or something like that.
Similarly on the sector and speed trap average you need to have passed that point on the track.
Got an idea?
Got an idea how to look at something or a topic that is interesting, let me know. There are always new and better ways to think about things.
What software do you use?
It used to just be quick and dirty excel based. Recently I developed a few Python tools to look at this.
Older posts could show the excel output because I am super lazy and didn’t just hit Shift Enter in Python for a particular race and imported charts already done.
I will go back to older races, and these posts will be the Python output, but dated around when the race happened.
I’ve seen this before.
Quite possibly. This is often discussed on the Motorsport forum TenTenths.
Off topic.
