I have a bit of an explanation as to why it sometimes happens, this is particular for the Boaro-incident yesterday.
Basically they enter the circuit, ride almost the entire circuit before crossing the line to begin the three circuits. Maybe Boaro simply thought they were counting the circuits from the moment they entered the circuit. I and the people standing next to me certainly had our doubts
About the Henderson-incident (and yes, I know he was kidding!); it took a few seconds for me to realise that him and his companions were not, in fact, in the front about the time it took for the peloton to arive a few seconds later.
