A r t i c l e 2 4 - Team time trials Teams start their team
time trial at 5 minute intervals in the reverse order of the
team ranking established following the 3rd stage. [...] The
stage ranking is established for each of the teams based on
the finishing time of the 5th rider in each team (to the
nearest hundredth of a second). An identical time is given
to all teammates who arrive within this same time, even if
they actually finish quicker. The procedure for establishing
the general individual time ranking is as follows: Times for
all riders are calculated according to the gap between them
and the 5th man of the winning team (scratch time). If this
gap is less than that given in the table below, then the
actual time recorded by the timekeepers will be taken. If
the gap is more than that given in the table below, then the
rider will receive the time of the winning team plus the
additional number of seconds indicated in the table below
according to the place of their team.[...] Riders who arrive
on their own after the 5th rider in their team will be
credited for the general ranking with the actual time they
took to complete the stage. However, riders finishing
outside of the permitted finishing times (coefficient 6)
will be disqualified. As far as the general team ranking is
concerned, the actual time of the 5th man in each team will
be the time recorded for this ranking. [...]
The cited table is missing. However, CN claims it is 10
seconds per place to 15th, 5 seconds per place after that.
This needs serious work. Consider the following:
Team A: 70:00 (all riders A0-A8) Team B: 75:00 (riders
B0-7) Team B: 75:01 (rider B8) Team C: 80 minutes (all
riders C0-C8)
Individual GC from this stage: A0-A8: 70:00 B0-B7: @ :10
C0-C8: @ :20
B8 : @ 5:01
Huh? The guy finishes 1 second back from his team, and loses
5 minutes as a result? Mind the gaps, guys.
This is an extreme example. However, it could easily occur
that a 1 second gap results in losses of more than a minute.
For 2005 an additional rule is needed -- no rider can lose
more time relative to his team time than the actual
difference in time between the rider and the team.
But this is really too complicated. If they want to cap the
time gaps, do a numerical transform on the times. Calculate
times the old fashion way. The winning team gets its time.
For the remaining teams, a transformed time gap dt' is
calculated from the actual time gap dt, as follows:
exp[2 dt/t0] - 1
dt' = -------------------- t0
exp[2 dt/t0] + 1
with t0 = 2.5 minutes, for example.
This would yield the following conversion:
dt dt'
(s) (s)0 1 1 5 5 10 10 20 20 30 30 60 57 120 100 180 125
240 138 300 145 600 150
Too complicated? Hardly, compared to the existing rules. One
step. Go faster, score better. That's not so complicated.
