Great work Volderke, but i didn't read it because:
1/ We know he had a flat, it is acknowledged in the stage report and verified by a UCI commissaire.
2/ From his Strava file, we can see he was actually going 4s faster than Fred Wright who finished with Roglic's group, which seems highly unlikely to be doing uphill on a flat tire. And since we know he had a flat tire (see #1), it is safe to assume the point where he punctured is where he suddenly lost speed on his Strava segment, which is roughly 140 meters before he stopped. Being well within 3k from the finish. Even in case people still doubt the validity of the UCI report, there would be no logical reason for him to fake a puncture considering he was going faster than someone from the front group, unless he would have been distanced before that, which doesn't match up with the timeline as explained in the next point.
3/ As a result the only possible way Remco should not get the same time as the peloton, is in case he were dropped by at least 4s from the peloton, before he punctured. But again, looking at his Strava file this seems highly unlikely. Furthermore, there is a fan video that shows him stopping roughly 50s after Roglic passes by, which would put him very close to Roglic at the moment he actually punctured, so impossible for him to have been dropped from the peloton.
4/ This also means it is highly unlikely Roglic attacked because he saw Evenepoel had a puncture.
