offical tour times most of the time are completely wrong by the way
also it's very risky to take times from video footage. you take it only if you watch it and you are 100% sure that the file is not corrupted(ads cut and etc...). the best is that you have two different broadcasts to compare of every ascent(RAI or Teledeporte,Eurosport)...for instance i don't think you could find an accurate video for the bonascre 2001 on youtube at all
