Does Standard Servo actually turn 180 degrees?

The spec states the server turns 180 degrees but the "Board of Education Rev" Basic stamp kit's example on goes from 10 o'clock to 2 o'clock. How do I make it go from 9 o'clock to 3 o'clock?

    Sometimes servos need a wider range of control pulses. The usual range is 1ms to 2ms (PULSOUT <pin>,500 to 1000). It can be as wide as 0.5ms to 2.5ms (PULSOUT <pin>,250 to 1250). Try the wider range in the sample program.

    There's no real standard for servo range of motion. If you need accurate information, you have to rely on the manufacturer's datasheet which should specify the range of motion and the range of control pulses that it will accept to achieve that motion. Even so, there is some small variation from servo to servo.
