Really i don´t know about radar- if it is wrong or not, but they are always some talking about radars- in davis cup and other tournaments too, but i think now in 2011 technology world it can´t be much wrong- maybe few mph but thats all. Dent never equaled Roddick´s 155mph officialy- maybe on training who knows. Ivo Karlovic hold officialy 2nd fastest serve i think 153mph but i am not sure. Raonic hit 145mph his maximum in that contest- what is about 233kmh and he hit 230kmh at AO too- so it can be right and that 151 mph he hit 2cm long was reayll i think fastest his serve in that competition. But the think is that Raonic can be stronger physically or make his swing even better and alredy is capable of hitting 145-150 maximum so i think he has really gret chance to break Andy´s record or equal it. And Verdasco many times when you look in GS tournaments statistics- is in top 10, once he was in top 5 fastest serves- and Roddick obviouslyl still can hit fast serve too so maybe that radar is correct after all...
I probably exaggerated a little, but as you can see on the list on the post below you, San Jose is overrepresented.
Raonic may very well challenge Roddick nevertheless.
