Zinoviev Letter said:You are right that the 3 km rule can create an anomaly when some riders avoid the crash and still manage to lose time on the biggest remaining group. In this case though, nobody really gives a donkey's ball hair about the GC time of the likes of EBH anyway.
The anomaly in this case is not in the strange GC times of people dropped on the final climb, but that the time lost by those behind is much larger than it would have been had that second crash (which had no time consequences as per the rules) not happened - they were 40 seconds behind, and suddenly lost 50 seconds thanks to that crash.
Now, not that this did happen, and it's pure conspiracy theorist nonsense, it would have been feasible, given that the second major group all came in together and without really forcing the pace, that once the likes of Andy Schleck, Gesink and Leipheimer had crashed, and that the road was blocked, what onus is there on them to get out of the road? They may as well just block it and hold up Contador, since they're going to get given the same time as the bunch ahead anyway.
It's a system that works absolutely fine 95% of the time. Just occasionally it lends itself to certain abuses and creates certain unfairness. Today was one of those occasions.
