F1 2011 Review - Grid/Final Classification Deltas

How does each team fare in terms changes between starting grid position and final classification across the races?



Note that position changes may be due to cars dropping out, although I still haven't found a good way of representing this yet. I guess one approach would be to identify the number of cars that dropped out in each race that started ahead of each car for each race, but I'm not sure how to calculate that (yet....?!)

In the meantime, here's an augmented version of the above chart that identifies the number of cars that were not classified at the end of each race:

In this case, the line extends from grid position to final classification, and is coloured green for an improvement, red for a drop. The grey circle highlights the grid position, the grey + denotes the number of cars that were unclassified at the end of the race.

The R code used to generate the charts in this post from the raw data in a Google spreadsheet:
