Henk, we may not agree (and that is all right!), but I don't buy your arguments. If a driver can't find the motivation to fight for an 8th place finish because it doesn't pay points, then well, it's his decision and I can't blame him, but he'll be a 9th place finisher for me the same as any other 9th place finisher. And if a driver decides that a third place is enough because he is "looking at the bigger picture", then that's okay, too, and I bet it has happened many times, but it doesn't change my view of his performance on that given day: a third place finisher, not a winner. I don't see a problem with rating driver performances entirely on results, it's the only objective measure. Sure, it's fun to speculate about the cement dust at Gazometer, the last drops of fuel left in Ron's can and the thousands of stories that surround racing, but in the end one driver gets the garlands, the champagne amd the cheque, and that's what all others aspire to. I'm all for deep analysis why a particular car failed after leading for 200 miles, and why a driver got involved in an accident not of his own, but for an overview of who's hot and who's not, the only fair way to do it is to look at the results, pure and simple, especially when we are looking at big time intervals. Good luck and bad luck often have a way to cancel out each other, and if not, well that's life.
As for team orders, they are as old as the sport - Bugatti and Alfa Romeo were famous for deciding who was to win on a given day, and even Mercedes was tayloring races to suit their lead driver, be it Lautenschlager or Caracciola. Do we know whether de Knyff held back to let Charron win? No, we don't, and we don't need to. I have long dithered over whether to include hippodromed IMCA races in my rankings, but to hell with it, it doesn't really matter. Neither Sig Haugdahl nor Gus Schrader or Emory Collins make it into leading positions in my rankings, hippodroming or not. Reality has a way of sorting things out, I discovered: big races can't be hippodromed because drivers are too competitive by nature, and small fry doesn't matter much. And Barrichello wouldn't have won more races without Ferrari team orders, because he wouldn't have driven a competitive car in so many races - you sign your contract, and you take the good with the bad. It has always been thus, and will always be...
