Get perspective. He gained 7 seconds. 0 of which he would have had, without a crash. He's going to lose 2 MINUTES in the last time trial. The number of further finishes where he can get away in the last kilometer and have a crash give him a gap due to rain is, what, 3 more? So 21 seconds goes into 2 minutes almost 6 times.
The final time trial is a kicker. But I can easily see Vino taking back 1min plus in a mountain stage and not getting dropped.
