Some of the dullest Tour years were Indurain's. No power meters or race radios then, simply ride to threshold up the mountains and smash the TTs. Likewise half of Armstrong's wins were without radio and no power meters and almost as dull too with a team throttling attacks riding to perceived threshold and HR, but at least he won a couple of stages unlike Indurain. If Indurain and also Armstrong's team can climb to threshold to kill the race without power and race radio, perhaps Bertie simply doesn't want to accept his time has passed and his way of racing more for fans entertainment than to increase your chance of winning have come to an end. It's bad news for the fans, but how much of professional sport should be about entertainment and how much about winning?
Also, the study by Gaël Guegan concluded using race radio actually rewards the brave and does not correlate with the outcome of a race in a negative way.
