S1: sports mode faster than AV mode?
Actually I think he meant that u use a fast shutter speed, but u choose the slowest one which enables you to catch the action without bluriness because there are contraints of light availability and since the S1 doesn't have amazing high ISO capability, you can't raise it much.
In the end, the slowest shutter speed is to get enough light. But its the slowest on the fast side.
