Yeah, some people seem to think 3 or 4 degrees is something sizeable.I certainly agree with him. As Brumby says, with Murali's doosra measured at 14 degrees when he knew he was being test, it's reasonable to think he's gone over that at some stage in match conditions. With McGrath measured at 11 degrees while being tested, it's pretty unlikely that he's never reached 15 degrees either at some stage in a match condition. And if someone with McGrath's action has done it, there won't be many players who haven't.
It isn't. There are 360 degrees in a circle. 3 or 4 degrees has to have one hell of an acute measurement tool to even pick it up. The naked-eye has not the remotest of hope of doing so.
You'd have to look very closely at a still image of a 1mm-thick line to notice a difference between 13deg and 16deg. To do so with an arm moving at a very fast speed is completely and totally impossible.
