That's wikipedia, that's not an official source in any way, a website managed by volunteers. The official UCI website has the season's overview on their website, where obviously stages are part of the WT overview.
Is it really necessary to tell me what wiki is? No its not.
Are you saying that the wiki chart is not correct?
The UCI chart is so great that you linked right?
The wiki graph gives a quick glance at results, the UCI site does not.
I admittedly have a bad memory so after I posted that a Belgian hadn't won a WT race yet this year, I thought that I should check my memory. I went to the UCI first, but you have to click on each race, then final result, and then back out to the next race and so on. With stage races you have two more clicks if you want to see each stage result. One click or 200+ clicks, you choose.
To help you sleep better though, I will go delete my previous posts about this.
EDIT: Next time that someone asks you who won (pick the stage race you want) the TdF, I want you to list each stage winner not the GC winner.
