I mean, read this:
"During a period of pretty much unchecked technical development from 1989 to 1993 there was a decrease of 9 in the average number of overtakes over the whole period.
During a period of constant FIA rule changes from 2004 to 2008 there was an overall reduction of 1 overtake per race."
[...] By using two different units of measurement for the two different periods, it's clear that this study is trying to get a point accross, instead of reporting unbiased information.

No lies, no bias, just a reatively simple stastic. Please don't turn degrade this into a Max/FIA debate.

Miguel wrote:It's not that simple. I'd actually say it would work the opposite way. Take in mind that the diffuser is not as sensitive as a front wing to the wake caused by a preceeding car.
Miguel wrote:Completely banning the diffuser would produce cars whose downforce depended mostly on the wings. I don't think that would produce more overtaking.
Miguel wrote:I am an armchair aerodynamist, and from this position I postulate that... I mean, I believe that the issue with the DDDs is the increased coupling between the diffuser and the rear wing. That is, I fear we're mostly back to 2008.
But I commend your effort to put this data together - it's the first time I've seen it all in one place and it must have taken a tremendous amount of time to compile.
I am indebted to the following members for their work in compiling the raw data: Michele Merlino, Brian W. Lawrence and GordonMurray.
The overtaking figures for each race do not include:
* Position changes on the first lap of the race
* Position changes due to drivers lapping backmarkers
* Positions gained in the pits
* Positions gained when a car has a serious technical problem; e.g. puncture, accident damage, etc.
This method was originally conceived by Brian W. Lawrence.
