Dr M. you have made my point for me. "They got their timing wrong". These riders were not outside the limit because they were beyond their physical capabilities or had some exceptional mishap. They were outside the limit because their cynical approach came unstuck. I note that in an answer to another post you say that they ,that is those outside the time limit, are trained to be cyclists and not mathematicians but it is exactly because they tried to act like mathematicians, and here I quote you again, "they got their timing wrong", that they finished beyond the limit.
I am perfectly aware of the rules and their operation but I fear that the organization will have made a rod for its own back and unless some serious thought is given to this particular fiasco we can get used to seeing half the riders drifting in day after day, apparently unconcerned,safe in the knowledge that the organization will not have the courage to eliminate half the field.
Look at the faces of those at the front of the race today. Were they trying? Yes they were. Look at the faces of those outside the limit. See the difference?
Your problem is you only see them in the last 50-100m and you're judging them on that. You haven't seen what they've been through for the past 100-200km. By the time they get into the last 500-1000m they know whether they're going to make it or not, the autobus leader (someone like Eisel or Hushovd) will get the nod from the race director and they'll ease up a little. That's why, to you, they don't look like they're 'trying'. They're just happy the day is over by that point.
If they come in a few seconds or a couple of minutes down, that's no big deal. If they have taken it 'easy' and come in 15-20 minutes late then they probably would be cut. There's an understanding between riders and race officials. It's existed for at least two decades.
The time limit isn't there for sporting reasons. It's so people don't have to hang around too long at the finish. It's not there with the intention of getting rid of riders. Sport is entertainment. Getting rid of half the field is stupid.
If some riders are taking it a little easy, then good for them - that's sensible. If some other rider is unnecessarily straining every sinew to finish five minutes faster, then more fool him. His DS will be having a word. Tomorrow in the TT, there will also be many riders going 2-3 minutes slower than they are actually capable of.
There's specific 'acceptable' time either. For example, on a 200km mountain stage ridden at between 32-33kph, then the cut off is 9%. But the difference in finishing times between 32.0 kph and 32.99 kph is
eleven minutes. What happens up front makes a big difference - but it doesn't make the autobus riders more or less capable. This year favourites have been attacking 60-90km from home - we haven't seen that for over a decade.
And finally, what should the time limit be? How good is good enough? What is 9% this year was 10% last year. On last year's rules they would have made the limit. With over 100 riders missing the time limit on at least one of two stages, the race directors will probably consider the reduction of the limit a mistake.
