Following on from F1 2011 Progress Throughout the Year, I've had a bit of a tinker (see the comments to that post) and pushed on the graphical reporting a little to try to get a better picture of how the teams improved their relative laptimes over the course of the season.
The following chart shows a loess model of the minimum laptimes recorded by each team as a percentage of the fastest overall laptime recorded for each race:
This approach may mask which team set the actual fastest lap for each race, of course. So to see the evolution of actual fastest laptimes recorded by each team as a percentage of the overall fastest lap set in each race, we need a more literal plot (results are thresholded to only show results within 108% of the fastest laptime set in each race):
So - a useful plot, or not (e.g. in the sense of writing an end of year review?)? Is the fastest relative laptime set per team actually a useful indicator of a team's progress, or not? Would it be useful to generate this sort of chart following each race during a season, as an indicator of team progress?
Next up, comparing the fastest laptimes between two arbitrary teams... err.. maybe...?!
PS Err, not, actually. Instead, F1 2011 Review - Qualifying Progress
