Dumoulin can, of course, release all of his data so that an objective assessment can be made of what has happened and if what he claims is true. Whether we find it believable or not isn't really helpful and that's kind of the point of this whole thread I think. There is a huge difference between perception and reality in many things, along with many reasons why people may wish to frame perception in a particular way. Cyclists are regarded as inherently untrustworthy, supposedly lying about doping, participating in Omerta, breaking rules elsewhere whenever they can. As such, I think we need to be very careful when believing something they have said that happens to confirm our own beliefs.This issue came up again in Dumoulin's comments on his ITT performance. I find it strange that we have some of the top guys going on record that they gave it their absolute best and were soundly beaten. Personally, I find it believable because this is not something that you would expect a sportsman to admit (even if it were true).
